You can put this solution on YOUR website!

1.PQ%5E2=PR%5E2%2BQR%5E2
2.SQ%5E2%2BRS%5E2=QR%5E2
3.PR%5E2=RS%5E2%2BPS%5E2
PQ=QS%2BSP=6%2B2=8
Substituting into 1, 2, and 3,
8%5E2=PR%5E2%2BQR%5E2
PR%5E2%2BQR%5E2=64
.
.
6%5E2%2BRS%5E2=QR%5E2
36%2BRS%5E2=QR%5E2
.
.
PR%5E2=RS%5E2%2B2%5E2
PR%5E2=RS%5E2%2B4
.
.
%28RS%5E2%2B4%29%2B%2836%2BRS%5E2%29=64
2RS%5E2%2B40=64
2RS%5E2=24
RS%5E2=12
So then,
RS%5E2=12
PR%5E2=12%2B4
PR%5E2=16
PR=4
True
