Four points B, C, Q and D lie on the same plane. Point B is 42km due southwest point Q. Point C is 50 km on a bearing of S60°E from Q. Point D is equidistant from B, Q and C.

- Using the scale: 1cm represents 10km, construct a diagram showing the positions of B, C, Q and D.
- Determine the
- Distance between B and C
- Bearing of D from B

- Find the distance and bearing of D from C.
