Question

What is the value of x in the triangle? A) 289 B) 17 C) 15 D) 14.2

Answer 1

For this you would use Pythagorean theorem (a^2+b^2=c^2) a=15 and c=sqrt 514 plug the numbers in and you’ll be set

Answer 2

Hi! I don't know if I'm too late or not, but as I just answered the question on my own, I can confirm to you that the answer is:
 B) 17
At first, I thought that the length of x and 15 were equal so that's what I had chosen. It was incorrect, so taking advantage of the retry, I looked at the shape slightly closer, and noticed that angle x was slightly longer. 
 Long story short the answer is B) 17.
