B is west of A, find the bearing of B from A

Step by step

The question

Question: B is west of A: find the bearing of B from A.

1 Draw the north line

A bearing starts at the north line.

It is measured clockwise, the way a clock turns, and written with 3 figures.

2 Measure clockwise

From north, turning clockwise to west: 270°.

West is three right angles from north: 270°.

With 3 figures: 270°.

Careful!

A bearing always has 3 figures.

We fill with zeros in front.

3 Check

Let's check: measured from north, clockwise, with 3 figures.

So it is right!

Let's look back.

First: draw the north line.

Then: measure clockwise.

Last: check.
