**Created using the work of**- Timur - Side length of a triangle

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

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.
