Question

The diagram shows the position of two towns, Alton and Barking.

The bearing of Barking from Alton is bº.
The bearing of Alton from Barking is 6bº.
No
Calculate the 3-figure bearing of Alton from Barking.​

Answer 1

216°

Explanation:

The difference between the bearing from B to A and the bearing from A to B is 180°. Here, the difference between the two bearings is ...

6b -b = 180°

b = 180°/5 = 36°

6b = 6·36° = 216°

The bearing of Alton from Barking is 216°.
