ΔABC is similar to ΔFED. Answer the questions to find the length of DF .
1. Which side in ΔFED does AB in ΔABC correspond to?
Write your answer in the space below.
2. Which side in ΔFED does CB in ΔABC correspond to?
Answers
Step-by-step explanation:
ΔABC is similar to ΔFED.
AB are the first 2 letters in ΔABC. Similarly, FE are the first 2 letters in ΔFED.
Hence side AB corresponds to side FE.
CB are the last 2 letters in ΔABC. Similarly, DE are the last 2 letters in ΔFED.
Hence side CB corresponds to side DE.
Answer:
1. EF in ΔFED corresponds to AB in ΔABC.
2. DE in ΔFED corresponds to CB in ΔABC.
3. The length of DF is 10.
Step-by-step explanation:
Given: ΔABC is similar to ΔFED. Find the length of DF.
To Find: The length of side DF in ΔFED
Since, ΔFED is a right-angled triangle and also similar to ΔABC,
Applying similarity of triangles principle,
AB = 4 , EF = 8
BC = 3 , DE = 6
Now, applying Pythagorean theorem on ΔFED,
Hypotenuse² = Length² + Base²
⇒ DF² = DE² + EF²
⇒ DF² = 6² + 8²
⇒ DF² = 100
⇒ DF = √100
⇒ DF = 10
Final Answer: Hence the length of side DF is 10.

Jeremy built an office with a floor area of 55/14 square feet. The office is rectangular in shape. If the length of the room is 8 1/2 feet, what is the width of the room?
Answers
Answer:
110/289 feet
Step-by-step explanation:
Step one:
given data
Area of the floor= 55/14 square feet.
The length of the floor= 8 1/2 feet-----convert to simple fraction= 17/2 feet
Step two:
The expression for the area of the room is
Area= L*W
55/14= 17/2*W
55/14=17W/2
cross multiply
17W*14=55*2
289W=110
divide both sides by 289
W= 110/289 feet

M<2=x+88 can you please tell me the answer for this
Answers
Answer:
Answer: A) -8
Step-by-step explanation:
The image shows the triangle where it can be noted that two of its sides are congruent (according to the tick marks). This forms an isosceles triangle that also has two congruent angles as shown in the image below.
The other angle (2) has a measure of x+88.
The sum of the internal angles of the triangle must be 180°, thus:
x + 88 + 50 + 50 = 180
Simplifying:
x + 188 = 180
x = 180 - 188 = -8
x = -8
Answer: A) -8

ou go to the store and buy jeans for $40, a shirt for $20, and a jacket for $60. You have a coupon for 35% off. What is the sale price?
Answers
Answer:
SAME AS THIS
Explanation:
County A: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$75 * 0.0725 = $5.4375
Add the original price and the sales tax.
$75 + $5.4375 = $80.4375
County B: Multiply the price by the sales tax to find out how much money the sales tax will add. Remember to convert percent to decimal!
$70 * 0.08 = $5.6
Add the original price and the sales tax.
$70 + $5.6 = $75.6
Then take the difference.
80.4375 – 75.6 = 4.8375
Round to the nearest hundredth: $4.84
Answer:
the sale price would be $78
Step-by-step explanation:
add up all the prices to get 120

find the slope of the line which is perpendicular to the line 7 x + 11 Y - 2=0
Answers
Answer:
[tex]\huge\boxed{slope=-\dfrac{7}{11}}[/tex]
Step-by-step explanation:
METHOD 1The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
[tex]m[/tex] - slope
[tex]b[/tex] - y-intercept
We have the equation in the general form [tex](Ax+By+C=0)[/tex].
Convert to the slope-intercept form:
[tex]7x+11y-2=0[/tex] subtract 7x from both sides
[tex]11y-2=-7x[/tex] add 2 to both sides
[tex]11y=-7x+2[/tex] divide both sides by 11
[tex]y=-\dfrac{7}{11}x+\dfrac{2}{11}[/tex]
METHOD 2The general form of an equation of a line:
[tex]Ax+By+C=0[/tex]
The slope:
[tex]m=\dfrac{-A}{B}[/tex]
We have
[tex]7x+11y-2=0\\\\A=7;\ B=11;\ C=-2[/tex]
Substitute:
[tex]m=\dfrac{-7}{11}=-\dfrac{7}{11}[/tex]
