Question

# Find: a) QR

b) 𝑚∠𝑃𝑄𝑇

Hint:

### Observe the figure carefully and notice which sides/ angles are equal

## The correct answer is: a) QR = 22 inches, b) ∠𝑃𝑄𝑇 = 90

### SOL – (a) In the figure, it is shown that PQ = QR and

PQ = 22 in.

QR = 22 inches

(b) PR is a straight line ∠ PQR = 180°

∠PQT + ∠ RQT = 180° ---- (1)

It is given that ∠ RQT = 90°

Substituting in (1)

We get, ∠PQT + 90° = 180°

∠PQT = 180° - 90°

∠PQT = 90°.
