This question involves bearings and trigonometry. A boat leaves a dock at point A and travels for a distance of 15 km to point B on a bearing of 135°. The boat then changes course and travels for a distance of 8 km to point C on a bearing of 060°.

Illustrate the above information in a clearly labelled diagram.
