## 7. Angles from Bearings

Given bearings going counter-clockwise around a loop traverse, compute the interior angles at each point.

Unlike computing directions from angles, it doesn't matter where to start or in what order or direction to compute the interior angles.

Drawing sketches helps visualize how to combine the bearings at a point to compute the angle.
