Points X, Y, and Z are on the sides QR , PR, and PQ respectively, of right triangle PQR such that PZXY is a square. If PQ=12 and PR=8, then what is the side length of the square?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Triangles PQR and ZQX are similar!
Square side => a
XZ / (PQ - PZ) = PR / PQ
a / (12 - a) = 8 / 12
a = 4.8
