You start at the origin on an ay plane. You walk 20 meters at an angle of 25 degrees north of the +x axis. After that, you turn, then walk 20 metors at an angle 45 degrees north of the +x axis. Finally, you turn and walk 10 meters at an angle 15 degrees south of the +x axis. Your friend, still at the origin, walks in a straight line to you in the fastest route. What angle do thoy take, and how many moters do they go?
