Question:

In the given figure, PQRS is a cyclic quadrilateral.  What is the measure of the angle PQR if PQ is parallel to SR?

Options:

75°

105° 

 110°

60°

Correct Answer:

105° 

Explanation:

∠P + ∠R = 180° (opposite angle of cyclic quadrilateral)

∠SRQ = 180° - 105° = 75°

∠R+∠Q = 180° (PQ llRS)

∠PQR = 180° - 75° = 105°
