Question

Please help me in this​

Answer 1

Step-by-step explanation:

we r using Pythagoras ka theorom

pq²+pr²=qr². (1) as angle p=90

qm²+mp²=pq². (2) as angle m =90

pm²+mr²=pr². .(3).

pq²+pr²=(qm+mr)²

=qm²+2(qm)(mr)+ mr²

qm²+mp² + pm²+ mr² = qm²+2(qm)(mr)+mr²

2mp²=2(qm)(mr)

mp²=qm×mr

(10)²=(8)×mr

100/8=mr

12.5 =mr

now qr=qm+mr=8+12.5

=20.5

Answer:

The answer is 20.5
