Q1. Find the measure of angle 1. Show your work.


Q2. Find the measure of angle 2. Show your work.


Q3. Find x. Show your work. ​

Answer:

x = 0

x = 2

x = -2

Step-by-step explanation:

f(x) = [tex]x^{3}[/tex] - 4x

Factor

f(x) = x ( [tex]x^{2}[/tex] - 4)

f(x) = x ( ( x - 2 ) ( x + 2 ) )

zeros;

x = 0

x = 2

x = -2

Answer:

3 : 8 D

3 shaded to 8 total sections

Answer:

15 rooms

Step-by-step explanation:

18/6 = 3 so multiply 3 times 5 and that equals 15!

Answer:

15 rooms.

Step-by-step explanation:

since they can clean 5 rooms in 6 hours, and it's asking how many rooms they can clean in 18 hours:

5/6=x/18

solve for x:

6x=90

x=15

Or you could've just multiplied 5 by 3 since 6(3)=18.

Answer:

a= 25.69, b=23.12, c=131.119

Step-by-step explanation:

[tex]cosa=\frac{B^{2} +C^{2} -A^{2} }{2BC} \\ =\frac{79.59}{88.32} \\ a = 25.69[/tex]

[tex]cos(b)=\frac{A^{2} +C^{2} -B^{2} }{2AC} \\ =\frac{89.69}{97.52}\\ b=23.12\\c=180-23.12-25.69\\ = 131.119[/tex]

Answer: Part A = 12 candles per hour

Step-by-step explanation:

48/4 = 12

Answer:

x ≈ 13.5

Step-by-step explanation:

Using the sine rule in the triangle, then

[tex]\frac{sin34}{x}[/tex] = [tex]\frac{sin27}{11}[/tex] ( cross- multiply )

x × sin27° = 11 × sin34° ( divide both sides by sin27° )

x = [tex]\frac{11sin34}{sin27}[/tex] ≈ 13.5 ( to the nearest tenth )

Answer:

Each interior angle of quadrilateral will be less than 180 degrees.

Step-by-step explanation:

A quadrilateral is a geometric shape which has four sides and 4 vertices. The given quadrilateral has 4 vertices and its two dimensional. The quadrilateral has angles less than 180 degrees. All of its angles are less than 180 degrees which are the vertices points on the quadrilateral.

Step-by-step explanation:

I don't know what your talking about, but here's my solution:

8 x 5 x 4 x 6 = 960cm

Answer: 960cm

Answer:

[tex]20.1\ \text{feet}[/tex]

Step-by-step explanation:

The given relation is

[tex]5x^2-2025=0[/tex]

where [tex]x[/tex] is the portion of walkway in which the person walks

Rearranging the equation we get

[tex]5x^2=2025\\\Rightarrow x^2=\dfrac{2025}{5}\\\Rightarrow x^2=405\\\Rightarrow x=\sqrt{405}\\\Rightarrow x=20.124\approx 20.1\ \text{feet}[/tex]

The length of the portion of the walkway labeled [tex]x[/tex] is [tex]20.1\ \text{feet}[/tex].

Answer:

5/6*2/3=10/18

Answer:

-250...? Please specify.

Step-by-step explanation:

Answer:

90 5/6

Step-by-step explanation:

23 + 67 + 1/2 + 1/3

= 90 + 3/6 + 2/6

Answer:

ASA postulate

Step-by-step explanation:

SO when you look at the triangle, you see that there are three marks on the triangle.

There are two different kinds of marks, the curved marks mean angles (and they are on an angle so it is easy to remember.) and the small tick mark means a line (it is also on the line) so you go from one side to another when you name the postulate.

So I typically go from left to right and so if I start with the angle on the left it would be A (angle) S (side) A (angle) because there are two angles and one side named that are the same as the other triangle

Answer:

503.2 mi²

Step-by-step explanation:

The amount of impact could be obtained by finding the area of the Circumference ; which is the measure of the crater :

Circumference, C = 79.5

Area of circle = πr²

Radius, r :

From ; C = 2πr

79.5 = 2 * 3.14 * r

79.5 = 6.28r

r = 79.5 /6.28

r = 12.659235

Area of circle, A : πr²

A = 3.14 * 12.659235^2

A = 503.2045646656065

A = 503.2 mi²

Answer:

I'm not going to do it for you but just offer the way I would do it.

1. Figure the overall area. Multiply the overall width by the overall length to get the overall area. If the overall length is not given, you'll have to add up from the numbers that are given.

2. Figure the area of each cutout. Again, length x width. Again, if they are not given, you'll have to do a little math with what you are given.

3. Subtract the area of each cutout from the overall area.

Answer:

x=2, y=-1

Step-by-step explanation:

Remember: Multiply each equation by a suitable number so that the two equations have the same leading coefficient. Then, go from there.

Answer:

29%

Step-by-step explanation:

since 5 out of 17 bring their own lunch, you would simply do 5/17, or 5 ÷ 17. and then change that decimal to a percentage by moving the decimal point over to the right twice.

5÷17=.29

.29=29%

Answer:

The equation of the line passing through the point (1,-4) and making an angle of 135º ​will be:

Step-by-step explanation:

Given the point (1, -4)

Given that the line makes an angle of 135º.

so

Slope = m = tan 135º = -1

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = -1 and the point (1,-4)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-\left(-4\right)=-1\cdot \left(x-1\right)[/tex]

[tex]y+4=-\left(x-1\right)[/tex]

subtract 4 from both sides

[tex]y+4-4=-\left(x-1\right)-4[/tex]

simplify

[tex]y=-x-3[/tex]

Therefore, the equation of the line passing through the point (1,-4) and making an angle of 135º ​will be:
