A boy scout ‘s girl scout girlfriend to test his scouting abilities has hidden her girl scout cookies somewhere in the forest and has given him the directions to retrieve them, along with a time limit. The directions tell him to 1) walk 400 m at an angle 45 degrees, 2) walk for 500 m at an angle of 150, 3) walk for 450 m at an angle of 220 degrees, and finally 4) 200 m at angle of 350 degrees. How far away are the cookies? What angle are they from him?
