There are a few answers at these links, but I need in fractional form/radical form:
YZ = 283/30.
I am sorry, but that is incorrect, very close, however. (I don't know the actual ans., but based on Dragan's decimal, I can tell you are close.)
I had this same problem, and I needed it in fraction form as well. I am assuming that you need it in fractional/radical form because you use AoPS. You will find the radical answer here:https://web2.0calc.com/questions/can-anyone-solve-this_6.
Hope this helps!
