With TV's the quoted size means the diagonal length; so 15-in TV means 15 inches diagonally across.
So that means a right triangle with hypotenuse 15 and one side = 12.
Just calculate the other side using Pythagorean theorem: a^2 + b^2 = c^2.

… calculate the other side using Pythagorean theorem: a^2 + b^2 = c^2, where c is the length of the hypotenuse; a and b the lengths of the perpendicular sides.
