Sine RuleEasyQuestion 200033
Question
In triangle ABC, the sine rule states:
- Aa/sin A = b/sin B = c/sin CCorrect
- Ba/cos A = b/cos B = c/cos C
- Ca sin A = b sin B = c sin C
- Da² = b² + c² − 2bc cos A
Correct answer
a/sin A = b/sin B = c/sin C
Explanation
The sine rule relates each side to the sine of its opposite angle: a/sin A = b/sin B = c/sin C = 2R (circumradius).
