In wandering, a grizzly bear makes a displacement of 1586 m due west, followed by a displacement of 3289 m in a direction 30.0° north of west. What are the magnitude and the direction of the displacement needed for the bear to return to its starting point? Specify the direction relative to due east.

I believe you add the two vectors, but I am not sure whether to just add 1586+3289cos(30.0) or add something else as well?
