Question

If sin θ 1 , + sin θ 2 , + sin θ 3 = 3 , 0° θ 1 , θ 2 θ ≤ 90°, then cos θ 1 , + cos θ 2 , + cos θ 3 is _____
THE ONE WHO WILL ANSWER FIRST WILL BECOME AS BRAINALIST...​

Answer 1

Answer:

SIN THETA 1 +SIN THETA 2+SIN THETA 3 =3

THIS CAN ONLY BE POSSIBLE WHEN ALL THE THETA WILL BE 90 DEGREE(90 DEGREE1)

SO 3 COS 90= 0
