When we add the angle that has x° and the angle that has (4x-20)° we need to get 180°.
Mathematically: x° + (4x-20)° = 180°.
We solve for x:
x°+4x°-20°=180°, we put all numbers that we know on the right side and all unknowns on the left side:
5x°=200°, we divide by 5 and get:
x=40°
So the correct answer is D. x=40°.
Answer:
5+7*x
Step by step explanation.....
12.4 / 6.2 = 2
so other side of enlarged rectangle = 1.8 x 2 = 3.6
Perimeter of enlarged rectangle = 2(3.6 + 12.4) = 32
Answer: 32 feet
------------------------
Another way to do:
12.4 / 6.2 = 2
SF = 2
The original rectangle has a perimeter of 16
Perimeter of the enlarged rectangle = 16 x 2 = 32
Answer: 32 feet
