Step-by-step explanation:
step 1. (13x + 8) + (2x + 7) = 180 (definition of same side interior angles)
step 2. 15x + 15 = 180 (like terms)
step 3. 15x = 165 (subtract 15 from each side)
step 4. x = 11. (divide both sides by 15)

Answer:
![C = \pi (2x -2)](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20%282x%20-2%29)
Step-by-step explanation:
The perimeter of a circle is the circumference of the circle. To find it, use the formula
.
The diameter here is two times the radius x, d = 2x. But here it has been decreased by 2 so it becomes d = 2x - 2.
Substitute into the formula.
![C = \pi (2x -2)](https://tex.z-dn.net/?f=C%20%3D%20%5Cpi%20%282x%20-2%29)
B and d because you can rotate it to make the same shape
