A hiker starts at his camp and moves the following distances while exploring his surroundings: 72.0 m north, 2.60 ✕ 102 m east, 1.30 ✕ 102 m at an angle 30.0° north of east, and 1.50 ✕ 102 m south. Find his resultant displacement from camp. (Take east as the positive x-direction and north as the positive y-direction.)
