*Question from Rene: *

Geometry – Chapter 10 Review #14 answer book says x=12.8, but we get x=5. What do you think?

*Answer from Dr. Callahan:*

Yes – a bit deceptive here. I think yours is reasonable.

However, he is going by this. The long side of each is X and 8 so you get

x/8 = 8/5

x = 12.8

The main thing is to never trust the image to be to scale. But, give the information, it could be either way. So let me change the solution to be

x = 5 or x = 12.8

*Hope this helps,*
