Question

PQR is a right - angled triangle with angle R = 90°. Find measure of side QR if
PQ= 10cm and PR = 6cm​

Answer 1

Answer:

(QR)=8

Step-by-step explanation:

By Pythagoras Theorem,

We know that,

(Hypotenuse)^2=(Base)^2+(Altitude)^2

Therefore,

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

(10)^2=(QR)^2+(6)^2

(QR)^2+(6)^2=(10)^2

(QR)^2+36=100

(QR)^2=100-36

(QR)^2=64

(QR)=8
