Pat and Leslie are on a map-reading exercise. Pat is on a bearing of 312 from Leslie's position.
On what bearing should Pat walk to meet Leslie?

Maths Help suggests:

Sketch Plan of Pat and Leslie's position

A sketch plan (right) will help.


  • Bearings are measured Clockwise from North.
  • Exploit the fact that the 'North' arrows are parallel.

    You should recognise that the angles marked with the double line are equal.

    So, work out angle A: 360° - 312° = 48°.

    The required angle (shown in blue) is 180° - 48° = 132°
