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°.
