Please help!!! If the sin 60Á = square root of three over two, then which statement is true?

cos 30Á = square root of three over two, because the cosine and sine are complements

cos 120Á = square root of three over two, because the cosine and sine are supplements

cos 30Á = 0, because the cosine and sine are complements

cos 1200Á = 0, because the cosine and sine are supplements

Answer :

Cos(30°) = √(3)/2 because cos and sin are complements. The first option is correct.
