Answer 2

\[\sin \frac{ \pi }{ 6 } = \frac{ 1 }{ 2 } ~~~~~~ \cos \frac{ \pi }{ 6 } = \frac{ \sqrt{3} }{ 2 }\]

Answer 3

oh i think i got it one sec

Answer 4

(1+sqrt3)/2

Answer 5

umm do you know the standard triangle for 30 degrees and 60 degrees? You may need to use that

Answer 6

Haha I was just going to say, you could make the special triangles

Answer 7

yeah but someone recked it... by giving values for them -_-

Answer 8

Yeah, that's useless

Answer 9

giving direct answers is against code of conduct and that guy had to latex it -_-! I know this.. you need to memorize those triangles... it's useful for Calculus and in higher level math.

Answer 10

I love these triangles <3

Answer 11

but after finding those values, it's correct @Ssaharan
