i sort of remember how to do this... i think i'm not sure. i just don't know which one is A? like how do you think it's supposed to be labeled as? and what were the meanings of sin, cos, and tan again?

Use Google. Law of Sines, Law of Cosines and the likes.
Nobody's interested in conducting a classroom here.

Remember, in a right triangle, sin A = opposite/hypotenuse; cos A = adjacent/hypotenuse, tan A = opposite/adjacent.
