Question

If the cos 30° = square root 3 over 2, then the sin 60° = _____. 0, because the angles are complementary 1 over 2, because the angles are complementary square root 3 over 2, because the angles are complementary 1, because the angles are complementary

Answer 1

Answer:

$\frac{\sqrt{3} }{2}$, because the angles are complementary

Step-by-step explanation:

The sine and the cosine functions are complementary functions.

This means that;

$\cos(\theta)=\sin(90-\theta)$

Or

$\sin(\theta)=\cos(90-\theta)$

If $\cos(30\degree)=\frac{\sqrt{3}}{2}$, then

$\sin(60\degree)=\frac{\sqrt{3}}{2}$

The correct answer is

$\frac{\sqrt{3} }{2}$, because the angles are complementary

Answer 2

Well, the answer would be square root of 3 over 2 because of the unit circle. So, the answer choice should be which ever one involved square root 3 over 2
