Question

Does anyone know how you work out this bearings question???

Answer 1

It will be 45 because from A is 40 and B is 5 and 40+5=45

Answer 2

The bearing of A from B according to the diagram is 82.86°

Using trigonometric relations ;

• Tan B = opposite/ Adjacent

B = bearing of A from B

Now we have;

Tan B = 40 /5

Tan B = 8

Take the inverse value of the tangent ;

`B = Tan^(-1) (8)`

B = 82.86°

Hence, the bearing of A from B is 82.86°
