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
