An helicopter flies in a strange pattern, all at the same altitude of 5 km: 1) it flies 29 km in a direction 30.0° east of north, 2) it flies 20 km due south, and 3) it flies 10 km in a direction 30.0° north of west. How far did the helicopter end up from its starting point?

Answer 1

All angles are measured CCW from due east.

D = 29km[60o] + 20km[270o] + 10km[150o] =
