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

69°
66°
60°
63°

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

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

MCQ: The 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
