I wanted to detail the way I approached the problem and the solution I landed on (in hopes that someone will come along and tell me how much better it could have been). Sexagisimal and Angles In astronomy, we represent the coordinates of things on the sky using angles. This is convenient because we can essentially look at the sky as a big sphere with us at the middle and form a coordinate system similar to our latitude and longitude system.
