Side length of a triangle
This calculator computes side length of a triangle given two sides and angle between them (law of cosines)
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
Well, there are a lot of things you can find about triangles. I've already used this law for finding Triangle Angle Calculator, now I use it to find the length of the side opposite the angle.
