You are camping with two friends, Joe and Karl. Since all three of you like your privacy, you don't pitch your tents close together. Joe's tent is 16.0 from yours, in the direction 22.0 north of east. Karl's tent is 39.5 from yours, in the direction 39.5 south of east.
What is the distance between Karl's tent and Joe's tent?

You have two sides and the included angle of a triangle. The two sides are a = 12 and b = 39.5 long, and the included angle is C = 61.5 degrees. Use the law of cosines for the third side length, c.
c^2 = a^2 + b^2 -2ab cos C
