Question

If the sin 60 agrees equals the square root of three over two which statement is true

Answer 1

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

Explanation:

Answer 2

Given that

`\sin60^o= ( √(3) )/(2)`


`\cos 30^o =\sin(90-30)^o=\sin60^o=( √(3) )/(2)`,


`\cos 120^o =-\sin(180-120)^o=-\sin60^o=-( √(3) )/(2)`,


`\cos30^o\\eq0`,


`\cos120^o\\eq0`

Therefore, the true statement is

`\cos 30^o =\sin(90-30)^o=\sin60^o=( √(3) )/(2)`,
because the cosine and sine are complements.
