Find the value of x.

A. 20
B. 17
C. 22
D. 15

Explanation:

Use the chord intersecting theorem

The pieces of each chord multiply to the same products

(x-5)*(x-8) = x*(x-11)

x^2-13x+40 = x^2-11x

-13x+40 = -11x x^2 terms cancel

40 = -11x+13x add 13x to both sides

40 = 2x

2x = 40

x = 40/2   divide both sides by 2

x = 20

step-by-step explanation:

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
