Need help with this problem. (Algebra 2)

[Nkrusch123]

I have this problem here that I really cant solve. I've gone through all my notes, I've googled lessons and nothing. If someone could maybe help me on where to start, it'd be really helpful.

I do not.

I do not.

Do you know the meaning of:

"sin of an angle? Or tangent of an angle ? Or cosine of an angle?

As skeeter is hinting big times, you should know the sides of the special 30-60-90 right triangle. Then you can multiple all sides by whatever value you like. What value do you like?
