Question

In the figure,∠ PQR = 90°, QN ⊥ PR, PN=12, NR=27, then find QN.​

Answer 1

Answer:

Step-by-step explanation: in triangle PQR, measure angle PQR = 90°

and QN is perpendicular to PR

THEREFORE, QN square = PN × NR

( geometric mean theorem)

= 9 × 16 . QN square = 144

Taking square root

Therefore, QN = 12 units
