If cos A + cos B + cos C = 3 than, what is the value of sin A + sin B + sin C?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 0
If Cos A + Cos B + Cos C = 3
Put A = 0º, B = 0º, C = 0º
Cos 0 + Cos 0 + Cos 0 = 1 + 1 + 1 = 3
It satisfies the question
SinA + Sin B + SinC = 0 + 0 + 0 = 0
