I'm attempting to write some code using the Ruby programming language that will give me the radius of an arc but the only pieces of information I have to work with are the arc length (L), the chord length (C), and the circular segment angle in degrees (A):

I'm hoping someone can show me how to insert L, C, and A into a formula that I can use in my code. I'm working with a CAD program that opens up access to certain pieces of information about each arc, but unfortunately radius isn't one of them, so I need to use the information I do have to find the radius.

Thanks so much for your time.
