You would have to find the adjacent and the hypotenuse. For example, if the adjacent was 80 degrees and the hypotenuse 29 you would do this: cos(29)/29 which wiuld give you 0.03. When finding the cosine its adjacent over hypotenuse. For sin its opposite over hhypotenuse and for tan its opposite over adjacent.

How do you find the angles of a triangle that is not a right triangle if you only have the side measurements?

If it's not a right angled triangle and you don't have any of the angles but have the values of all three sides, then you need to use something called the Cosine Rule.
