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

The answer is (a) cos 30° = square root of three over two, because the cosine and sine are complements

Step-by-step explanation:  Given that -

we are to select the correct statement from the given four options.

We know that sine and cosine functions are supplement of each other. So, we have

Thus, the correct option is (a) cos 30° = square root of three over two, because the cosine and sine are complements.

step-by-step explanation:

the first 5 right here the next 5 i will upload as separate question

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
