Sine Rule and Formula Multiple Choice Questions with Answers – PDF Download

MCQ 1: In a triangle ABC, if angle A = 72°, angle B = 48° and c = 9 cm then the Ĉ is:

1. 69°
2. 66°
3. 60°
4. 63°

MCQ 2: The sine rule for a triangle states that:

1. a/sin A = b/sin B = c/sin C
2. sin A/a = sin B/b = sin C/c
3. a/sin A + b/sin B + c/sin C
4. 2a/sin A = 2b/sin B = 2c/sin C
