In the diagram, PQRS is a parallelogram and ∠QRT = 30o. Find x

In the diagram, PQRS is a parallelogram and ∠QRT = 30^o. Find x

A.
95^o
B.
100^o
C.
120^o
D.
150^o

Correct Answer: Option D

Explanation

Since ∠QRS = 180^o – 30^o = 150^o and ∠SPQ = ∠QRS (theorem opp. angles in a parallelogram are equal) ∴ x = 150^o
