Answer:
Step-by-step explanation:
Since, lines l and m are parallel and a transverse is intersecting these lines.
5). (9x + 2)° = 119° [Alternate intrior angles]
9x = 117 ⇒ x = 13
6). (12x - 8)° + 104° = 180°
12x = 180 - 96
x = [tex]\frac{84}{12}[/tex] ⇒ x = 7
7). (5x + 7) = (8x - 71) [Alternate exterior angles]
8x - 5x = 71 + 7
3x = 78
x = 26
8). (4x - 7) = (7x - 61) [Corresponding angles]
7x - 4x = -7 + 61
3x = 54
x = 18
9). (9x + 25) = (13x - 19) [Corresponding angles]
13x - 9x = 25 + 19
4x = 44
x = 11
(13x - 19)° + (17y + 5)° = 180°[Linear pair of angles are supplementary]
(13×11) - 19 + 17y + 5 = 180
129 + 17y = 180
17y = 180 - 129
y = 3
10). (3x - 29) + (8y + 17) = 180 [linear pair of angles are supplementary]
3x + 8y = 180 + 12
3x + 8y = 192 -----(1)
(8y + 17) = (6x - 7) [Alternate exterior angles]
6x - 8y = 24
3x - 4y = 12 -----(2)
Equation (1) - equation (2)
(3x + 8y) - (3x - 4y) = 192 - 12
12y = 180
y = 15
From equation (1),
3x + 8(15) = 192
3x + 120 = 192
x = 24
11). (3x + 49)° = (7x - 23)° [Corresponding angles]
7x - 3x = 49 + 23
4x = 72 ⇒ x = 18
(11y - 1)° = (3x)° [Corresponding angles]
11y = 3×18 + 1
11y = 55 ⇒ y = 5
12). (5x - 38)° = (3x - 4)° [Corresponding angles]
5x - 3x = 38 - 4
2x = 34
x = 17
(7y - 20)° + (5x - 38)° + 90° = 180°
[Sum of interior angles of a triangle = 180°]
7y + 5x - 58 = 90
5x + 7y = 148
5×17 + 7y = 148
85 + 7y = 148
7y = 148 - 85
y = [tex]\frac{63}{7}=9[/tex]
Angles can be congruent based n several theorems; some of these theorems are: corresponding angles, vertical angles, alternate exterior angles and several others.
The values of x and y are:
5. [tex]\mathbf{x = 13}[/tex]6. [tex]\mathbf{x = 7}[/tex]7. [tex]\mathbf{x= 26}[/tex]8. [tex]\mathbf{x = 18}[/tex]9. [tex]\mathbf{x = 11}[/tex] and [tex]\mathbf{y = 7}[/tex]10. [tex]\mathbf{x = 24}[/tex] and [tex]\mathbf{y = 15}[/tex]11. [tex]\mathbf{x = 18}[/tex] and [tex]\mathbf{y =5}[/tex]12. [tex]\mathbf{x = 17}[/tex] and [tex]\mathbf{y=9}[/tex]Question 5:
Angles (9x + 2) and 119 are alternate angles.
Alternate angles are equal. So, we have:
[tex]\mathbf{9x +2 = 119}[/tex]
Subtract 2 from both sides
[tex]\mathbf{9x = 117}[/tex]
Divide both sides by 9
[tex]\mathbf{x = 13}[/tex]
Question 6:
Angles (12x - 8) and 104 are interior angles.
Interior angles add up to 180. So, we have:
[tex]\mathbf{12x -8 + 104 = 180}[/tex]
Collect like terms
[tex]\mathbf{12x = 180 - 104 + 8}[/tex]
[tex]\mathbf{12x = 84}[/tex]
Divide both sides by 12
[tex]\mathbf{x = 7}[/tex]
Question 7:
Angles (5x + 7) and (8x - 71) are alternate exterior angles.
Alternate exterior angles are equal. So, we have:
[tex]\mathbf{5x + 7 = 8x - 71}[/tex]
Collect like terms
[tex]\mathbf{8x - 5x= 71 + 7}[/tex]
[tex]\mathbf{3x= 78}[/tex]
Divide both sides by 3
[tex]\mathbf{x= 26}[/tex]
Question 8:
Angles (4x - 7) and (7x - 61) are corresponding angles.
Corresponding angles are equal. So, we have:
[tex]\mathbf{4x - 7 = 7x - 61}[/tex]
Collect like terms
[tex]\mathbf{4x - 7x = 7 - 61}[/tex]
[tex]\mathbf{- 3x = -54}[/tex]
Divide both sides by -3
[tex]\mathbf{x = 18}[/tex]
Question 9:
Angles (9x + 25) and (13x - 19) are corresponding angles.
Corresponding angles are equal. So, we have:
[tex]\mathbf{9x + 25 = 13x - 19}[/tex]
Collect like terms
[tex]\mathbf{9x -13x = -25 - 19}[/tex]
[tex]\mathbf{-4x = -44}[/tex]
Divide both sides by -4
[tex]\mathbf{x = 11}[/tex]
Angles (17y + 5) and (13x - 19) are supplementary angles.
So, we have:
[tex]\mathbf{17y + 5 = 13x - 19}[/tex]
Substitute 11 for x
[tex]\mathbf{17y + 5 = 13\times 11 - 19}[/tex]
[tex]\mathbf{17y + 5 = 124}[/tex]
Subtract 5 from both sides
[tex]\mathbf{17y = 119}[/tex]
Divide both sides by 17
[tex]\mathbf{y = 7}[/tex]
Question 10:
Angles (3x - 29) and (6x - 7) add up to 180
So, we have:
[tex]\mathbf{3x -29 + 6x - 7 = 180}[/tex]
Collect like terms
[tex]\mathbf{3x + 6x = 180 + 7 + 29}[/tex]
[tex]\mathbf{9x = 216}[/tex]
Divide both sides by 9
[tex]\mathbf{x = 24}[/tex]
Angles (3x - 29) and (8y + 17) are supplementary angles.
So, we have:
[tex]\mathbf{3x - 29 + 8y + 17 = 180}[/tex]
Substitute 24 for x
[tex]\mathbf{3 \times 24 - 29 + 8y + 17 = 180}[/tex]
[tex]\mathbf{43 + 8y + 17 = 180}[/tex]
Collect like terms
[tex]\mathbf{8y = 180 - 43 - 17}[/tex]
[tex]\mathbf{8y = 120}[/tex]
Divide both sides by 8
[tex]\mathbf{y = 15}[/tex]
Question 11:
Angles (7x - 23) and (49 + 3x) are corresponding angles
So, we have:
[tex]\mathbf{7x - 23 = 49 + 3x}[/tex]
Collect like terms
[tex]\mathbf{7x - 3x = 49 + 23}[/tex]
[tex]\mathbf{4x = 72}[/tex]
Divide both sides by 4
[tex]\mathbf{x = 18}[/tex]
Angles 3x and (11y - 1) are corresponding angles.
So, we have:
[tex]\mathbf{3x = 11y - 1}[/tex]
Substitute 18 for x
[tex]\mathbf{3 \times 18 = 11y - 1}[/tex]
[tex]\mathbf{54 = 11y - 1}[/tex]
Collect like terms
[tex]\mathbf{11y =54+ 1}[/tex]
[tex]\mathbf{11y =55}[/tex]
Divide both sides by 11
[tex]\mathbf{y =5}[/tex]
Question 12:
Angles (5x - 38) and (3x - 4) are corresponding angles
So, we have:
[tex]\mathbf{5x - 38 = 3x - 4}[/tex]
Collect like terms
[tex]\mathbf{5x - 3x = 38 - 4}[/tex]
[tex]\mathbf{2x = 34}[/tex]
Divide both sides by 2
[tex]\mathbf{x = 17}[/tex]
Angles (7y - 20) and (5x - 38) are angles at the other legs of a right-angled triangle.
So, we have:
[tex]\mathbf{7y - 20 +5x - 38 = 90}[/tex]
Substitute 17 for x
[tex]\mathbf{7y - 20 +5 \times 17 - 38 = 90}[/tex]
[tex]\mathbf{7y+ 27 = 90}[/tex]
Collect like terms
[tex]\mathbf{7y=- 27 +90}[/tex]
[tex]\mathbf{7y=63}[/tex]
Divide both sides by 7
[tex]\mathbf{y=9}[/tex]

one acute angle of right angled triangle is 63 degree find the other angle in degree
Answer:
x =27
Step-by-step explanation:
A right triangle has a 90 degree angle. It also has a 60 degree angle
The sum of the angles of a triangle are 180.
90+63+x = 180
153+x = 180
Subtract 153 from each side

2(4z−1)=3(z+2) Find value of z
Answer:
z=1.6
Step-by-step explanation:
Answer:
The answer is z = 8/5.
Step-by-step explanation:
first distribute the first parentheses you should get 8z-2=3(z+2)
second you would distribute the second group of parentheses you should get 8z-2=3z+6
third step would be combining like terms, move 3z over to 8z remember to substract then move -2 to the 6 be sure the add this time and you should end up with 5z=8
Lastly divide the 8 by the 5 so 8/5 and it cannot be simplified so the answer is z = 8/5

Three parallelograms are hinged at each vertex to create an arm that can extend and collapse for an exploratory spaceship robot. What is m<1?
Given:
Three parallelograms are hinged at each vertex.
To find:
The measure of angle 1.
Solution:
From the given figure it is clear that angle on the vertex = 122°.
Now let angle 2 be the vertex angle in second parallelogram as shown in below figure.
[tex]m\angle 2=122^\circ[/tex] (Vertically opposite angles)
Two consecutive angles of a parallelogram are supplementary angles.
[tex]m\angle 1+m\angle 2=180^\circ[/tex]
[tex]m\angle 1+122^\circ=180^\circ[/tex]
[tex]m\angle 1=180^\circ-122^\circ[/tex]
[tex]m\angle 1=58^\circ[/tex]
Therefore, the measure of angle 1 is 58°.

Kushner & Company is an architectural firm specializing in home remodeling for private clients and new office buildings for corporate clients. Kushner charges customers at a billing rate equal to 130% of the client's total job cost. A client's total job cost is a combination of (1) professional time spent on the client ($ 63 per hour cost of employing each professional) and (2) operating overhead allocated to the client's job. Kushner allocates operating overhead to jobs based on professional hours spent on the job. Kushner estimates its five professionals will incur a total of 10,000 professional hours working on client jobs during the year
Answer:
the question is incomplete so I looked for a similar question:
Besides the missing information, we are told that Li's job required 25 professional hours, 125 miles of travelling, 4 blueprint copies, and 15 secretarial hours.
total overhead = $233,000
total professional hours = 10,000
predetermined overhead allocation rate = $233,000 / 10,000 = $23.30 per professional hourcost of Li's job:
professional hours = 25 x $63 = $1,575
allocated overhead = 25 x $23.30 = $582.50
total = $2,157.50
billing to Mr. Li = $2,157.50 x 1.3 = $2,804.75if they used ABC costing, then allocation rates would be:
cost per mile = $6,000 / 15,000 miles = $0.40 per mile drivencost per blueprint copy = $32,000 / 1,000 = $32 per blueprint copycost per secretarial hour = $195,000 / 5,000 = $39 per hourif ABC costing was used, the cost of Li's job would have been:
professional hours = 25 x $63 = $1,575
125 miles x $0.40 = $50
4 blueprint copies x $32 = $128
15 secretarial hour x $39 = $585
total cost = $2,338
billing to Mr. Li = $2,338 x 1.3 = $3,039.40ABC costing is more exact, and therefore, it is more fair to customers (and the company also) since customers are charged based on what the company really spent on serving them.
