If the sin 30° = one over two, then which statement is true?

cos 150° = 0 because the cosine and sine are supplements

cos 60° = one over two because the cosine and sine are complements

cos 150° = 1 because the cosine and sine are supplements

cos 60° = 0 because the cosine and sine are complements
