Props to S.C. (MMSTC Class of 2018) for making a Mix-Up of the song! (It's really cool --- but I do find it a bit embarrassing!)
Two different videos with basic examples when you want to know the side opposite the given angel (or given SAS).

BTW, once you substitute your values, you can enter all of this directly into your calculator to compute.
