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

- 69°
- 66°
- 60°
- 63°

C

MCQ: Considering Cosine Rule of any triangle ABC, possible measures of angle A includes

- angle A is obtuse
- angle A is acute
- angle A is right-angle
- all of above

D

MCQ: Sine rule for a triangle states that

- a/sin A = b/sin B = c/sin C
- sin A/a = sin B/b = sin C/c
- a/sin A + b/sin B + c/sin C
- 2a/sin A = 2b/sin B = 2c/sin C
