Question 41
Angles and PolygonsIn the parallelogram PQRS above, find angle SQR.
- A.100°
- B.80°
- C.50°
- D.30°
Show the answer and explanation
Answer: A (100°)
Explanation
∠QSR = 50° (alternate to the 50° at Q). ∠PSR = 180° − 30° = 150°, so ∠SRQ = 30° (co-interior angles). Then ∠SQR = 180° − 50° − 30° = 100°.
