A boat leaves a dock at point A and travels for a distance of 15km to point B on a bearing of 135 degrees. The boat then changes course and travels for a distance of 8km to point C on a bearing of 060 degrees. Calculate, the distance AC, angles BCA and the bearing of A from C.? :confused:

Draw a picture, look at the angles, try drawing a line which goes through point B and perpendicular to line AC.
