Question

let me know the answer of question 10​

Answer 1

Answer:

Option (a):- 40°

Step-by-step explanation:

Angle PSQ = 90° (Angles in semicircle are of 90°)

Angle PSQ + Angle SPQ + Angle PQS = 180° (Angle sum property of a triangle)

90° + 50° + Angle SPQ = 180°

140° + Angle SPQ = 180°

Angle SPQ = 180° - 140°

Angle SPQ = 40°

Angle SPQ = Angle PSR

40° = Angle PSR

Therefore, measure of Angle PSR is 40°.
