How do you find a missing angle. Below is the implementation of the above approach. Using the Law of Cosines to Find the Third Side.
Set up an equation using a sohcahtoa ratio.
The hypotenuse is always opposite the right angle and it is always the longest side of the triangle. Calculate the semi perimeters of a triangle S. A2 b2 c2 Solve for the Length of the Hypotenuse c. If the angle between the sides of length S and L is very small close to zero as in the diagram below then T is only slightly larger then L - S.
