After I've written Pythagorean theorem calculator, I've recalled that the Pythagorean theorem is a special case of a more general theorem relating the lengths of sides in any triangle, the law of cosines

$c^2=a^2+b^2-2abcos\gamma$

Well, there are a lot of things you can find about triangles. I've already used this law for finding Triangle angles for given triangle sides, now I use it to find the length of the side opposite the angle.
