If the sin 60° = square root of three over two, then which statement is true? (6 points) cos 30° = square root of three over two, because the cosine and sine are complements cos 30° = 0, because the cosine and sine are complements cos 120° = square root of three over two, because the cosine and sine are supplements cos 120° = 0, because the cosine and sine are supplements
