Asked by Jenna
A dog searching for a bone walks 2.87 m south, then runs 22.5 m at an angle 30.5 north of east, and finally walks 5.91 m west. Find the direction of the dog's resultant displacement vector. Give your answer as an angle in degrees, with the angle measured counterclockwise from the line pointing straight East (North is 90, while South is -90).
