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,
