Correct Answer - Option 1 : 114°
Given:
∠SQR = 24°
Calculation:
∠QRS = 90° (Angle inscribed in a semicircle)
⇒ ∠SQR + ∠QRS + ∠RSQ = 180° [sum of interior angles of a triangle is 180°]
⇒ 24° + 90° + ∠RSQ = 180°
⇒ 114° + ∠RSQ = 180°
⇒ ∠RSQ = (180° – 114°)
⇒ ∠RSQ = 66°
Now,
∠QPS + ∠RSQ = 180° [sum of pair of opposite sides of cyclic quadrilateral is 180°]
⇒ ∠QPS + 66° = 180°
⇒ ∠QPS = (180° – 66°)
⇒ ∠QPS = 114°
∴ The required value of ∠QPS is 114°
