    I remember learning some trig in geo. You want to use one of the 3 most basic trig functions, don't think about cotan, csc, or sec for now

    You want to use either sine, cosine or tangent, abbrev. sin, cos or tan respectively

    There are three sides of a triangle: the hypotenuse, the long leg, and short leg. Yes, it is cosine

    Cos(theta), where theta is some angle, is adjacent/hypotenuse

    O is the opposite site of the angle, hypotenuse is the longest side, and adjacent is the side next to the angle

    You have to use arccosine in order to find the angle

    Think of it like this: if cos(x) = (4/7) then arcos(4/7) = x

    arccos looks like cos^-1(x), but the -1 is not an exponent, it's a just a symbol. So you don't actually take it to the -1 power

    Do you know which sides of the triangle are what, even if the angles are at different sides?

    sin/cos/tan are all relative to the angle, so adjacent and opposite can get mixed up sometimes :p
