For angleKMH with side lengths k,m, and h, use the law of cosines to write an equation to find the length of side m.
**
Law of Cosines:c^2=a^2+b^2-2*a*b*cosC
Use Law of Cosines when 2 sides and the included angle of a triangle are known, and you need to find the third side.
For given problem:
The two sides are h and k and their included angle is M. You need to find side m.
m^2=h^2+k^2-2*h*k *cos M
m=√(h^2+k^2-2*h*k *cos M)
