Question

if PQR is a triangle, right angled at P. PQ=10cm and PR=24cm, find BC when i get the number 676 how is the the easiest way to get 26cm
​

Answer 1

Answer:

By applying Pythagoras theorem in triangle PQR, we get (Hypotenuse)2 = (Perpendicular)2 + (Base)2

(QR)2 = (PQ)2 + (PR)2

(QR)2 = (10)2 + (24)2

(QR)2 = 100 + 576

(QR)2 = 676

QR = 26 cm

Thus, QR is equal to 26 cm.
