Two boats leave a harbour. One sails 9 km on a bearing of 030^circ and the other 12 km on a bearing of 120^circ. How far apart are they?

  1. 15 km
  2. 17 km
  3. 21 km
  4. 3 km
Answer

A) 15 km

The angle between the bearings is 120^circ - 30^circ = 90^circ, so the distance is 9^2 + 12^2 = 15 km. SLO M-09-B-27 · Application
