After I've wrote Side length of a right triangle by user's request, I've recalled that Pythagorean theorem is a special case of 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 lot of things you can find about triangle. I've already used this law for finding Triangle angles for given triangle sides, now I use it to find length of side opposite the angle.
