Question

Find the measure of FG. A. 9 B. 10 C. 11 D. 8

Answer 1

The answer is definitely x=11

Answer 2

x =11

Explanation:

(whole secant) x (external part) = (whole secant) x (external part)

( 15+x-2) * (x-2) = (19+x-3) * (x-3)

Combine like terms

(13+x) *(x-2) = (16+x) *(x-3)

Distribute

11x+x^2-26=13x+x^2-48

Subtract x^2 from each side

11x -26 = 13x -48

Subtract 11x from each side

-26 = 2x-48

Add 48 to each side

22 = 2x

Divide by 2

11 =x
