Question

Angle qpr=90°, seg pm perpendicular seg qr and q-m-r, pm=10 qm=8 find qr.

Answer 1

By property of geometric mean PM2=QM.MR Substiting the values 100÷8=12.5 MR=12.5 QR=QM+MR =8 +12.5 = 20.5 QR= 20.5

Answer 2

Answer:20.5

Step-by-step explanation:

as given in triangle PQR , ∠P=90°. it means ΔPQR is a right angle triangle . and PM⊥QR.

given that

PM=10

QM=8

as we know

PM²=QM* MR

⇒(10)²=8*MR

⇒100 = 8*MR

⇒MR = 12.5

so QR = QM+MR

=8+12.5

=20.5
