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

In the diagram, PQRS is a parallelogram and ∠QRT = 30o. Find x
  • A.
    95o
  • B.
    100o
  • C.
    120o
  • D.
    150o
Correct Answer: Option D
Explanation

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