For the same circle (PR a diameter, ∠QPR = 42°), calculate PRQ.
- A. 42°
- B. 58°
- C. 48°
- D. 90°
Verified working — step 1
PR is a diameter, so ∠PQR = 90°. In triangle PQR, ∠PRQ = 180° − 90° − 42° = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
