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.
