PQR - Euclid

Find the length of line segment PR - leg of the right triangle PQR.
PQ=17 cm
PS=15 cm
QS=8 cm;

Point S is the height touch point with a hypotenuse of the RQ.

Correct answer:

PR =  31.875 cm

Step-by-step explanation:

PQ=17 cm PS=15 cm QS=8 cm  PS2 = QS.SR  SR=QSPS2=8152=8225=28.125 cm  RQ=SR+QS=28.125+8=8289=36.125 cm  RQ2 = PR2 + RQ2  PR=RQ2PQ2=36.1252172=31.875 cm
