The question is as follows:

A kite has an 8-inch side and a 15-inch side, which form a right angle. Find the length of the diagonals of the kite.

I found the length of the vertical diagonal to be 17in, but I can't find the length of the horizontal diagonal. Any help will be greatly appreciated!

One diagonal can by found by pythagoras, $a^2+b^2=c^2$. Then the other can be found by expressing the area of a right triangle in two ways: $\frac12ab=\frac 12ch$.
