Answer 3

@xmoseje We need a picture of the triangle in order to do this.

Answer 4

i forgot

Answer 5

But the way to remember how to identify sin, cos, and tan is:
SOH
CAH
TOA
\[\sin = \frac{ opposite }{ hypotenuse }\]
\[\cos= \frac{ adjacent }{ hypotenuse }\]
\[\tan = \frac{ opposite }{ adjacent }\]

Answer 6

thnx

Answer 7

sin(a) so start at angle A then look at the opposite angle and put it over the hypotenuse.
