Please help!!!! If the cos 30° = square root 3 over 2, then the sin 60° = _____.

OpenStudy (dayakar):

sin 60 = cos 30

OpenStudy (dayakar):

do u know answer now

OpenStudy (ishipdestiel):

I don't think that's the answer, what about the square root 3 over 2?

MY GOD I LOVE YOUR NAME

OpenStudy (anonymous):

CHUCK*

OpenStudy (ishipdestiel):

Thank you

OpenStudy (anonymous):

;-; Thats all I came for sorry :)

OpenStudy (sagewilson):

sin60°=sin(90−30)=cos30=3√2 I hope this helps, btw its good to see fellow whovians, hunters and sherlockians.

OpenStudy (anonymous):

Yaay!!

OpenStudy (sagewilson):

@IshipDestiel do you understand or would you like me to explain?

OpenStudy (ishipdestiel):

Not really can you show me how you got that

OpenStudy (sagewilson):

I just searched the answer up online, but I'll give an explination.

OpenStudy (sagewilson):

Forget what I put before. I saw the same question http://assets.openstudy.com/updates/attachments/52dbe594e4b05a53debd1380-rindelly-1390142959379-screenshot20140119at9.42.59am.png Are these the same choices you have?

OpenStudy (ishipdestiel):

Yes

OpenStudy (sagewilson):

Your answer would be 3√2

OpenStudy (ishipdestiel):

because they are complementary?

OpenStudy (sagewilson):

This is because Sin 60 = .8660 and Cos30 = .8660, makeing them equal, so if Cos 30 = 3√2 so will sin60. In short, yes because they are complementary

OpenStudy (ishipdestiel):

Thank you so much, would you be able to help me with another one

OpenStudy (sagewilson):

I'd love to but I'm kinda busy at work + my own homework but when I manage to get a break I'll help you out.

OpenStudy (ishipdestiel):

Thank you so much. I appreciate everything you have done for me
