Question

Medal>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>If the sin 60° = square root of three over two, then which statement is true?

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

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

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

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

I'm pretty sure for the the first question it would be the first option @ArmyBoy97 or at least i want to say it is.

Answer 19

\[cos(30^o)=sin(60^o)=\frac{\sqrt{3}}{2}\]

Answer 20

The correct answer is:

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

Answer 21

ok and the second one?

Answer 22

\[Sin(10^o)=Cos(80^o)\]Always \[Sin(x)=Cos(90-x)\]

Answer 23

ok i understand d3xt3r

Answer 24

what about the second one

Answer 25

?

Answer 26

The answer is 10°; 80°
