Question

Need help with a geometry question, please.

Answer 1

Solve for x.

Answer 2

3 I think is there answer

Answer 3

I know x =2 as I can solve doing a long drawn out algebraic quadratic equation, Buis there a simpler geometric way?

Answer 4

*choices

Answer 5

@Holly00d1248 explain why you think 3 is the answer

Answer 6

So I can say \[x ^{2}+6x=16 ....per ..the..pathogorean..theorem\]

Answer 7

Leaving me with x^2+6x-16 = 0....or (x+8) (x-2) = 0 thus x=2. But this not shown as a way to solve in the text. Is there another way?

Answer 8

use the similarity of 2 triangles
