If the sin 60° is square root 3/2, then the cos ____° = _____. I answered this Already and I want to know if it is correct... I got 30; Square Root 3/2 30° ; 1/2 60° ; square root 2/2 30° ; square root 3/2 60° ; 1

Yes, sin and cos are complementary, so if sin x = y, cos (90-x) = y (if x is in degrees!)
