For the Cosine Rule of any triangle ABC, the b² is equal to
- a² - c² + 2ab cos A
- a³ + c³ - 3ab cos A
- a² + c² - 2ac cos B
- a² - c² 4bc cos A
For the Cosine Rule of any triangle ABC, the c² is equal to
- c² + a² + 2ac cos C
- a² + b² - 2ab cos C
- a² + b² + 2ab cos A
- a² - b² + 2ab sin A
In a triangle ABC, if angle A = 72°, angle B = 48° and c = 9 cm then the Ĉ is
- 69°
- 66°
- 60°
- 63°
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
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
