Help needed urgently
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=10 and PR=10, then what is the side length of the square?
2. Theorem of rays
\(\overline {PR}:x=\overline {PQ}:(\overline {PQ}-x)\\ 10:x=10:(10-x)\\ 10x=10\cdot (10-x)\\ 10x=100-10x\\20x=100\\ \color{blue}x=5\)
The side length of the square is 5.
