<em>Refer to attached</em>
Musah start point and movement is captured in the picture.
- 1. He moves 50 steps to North,
- 2. Then 25 steps to West,
- 3. Then 50 steps on a bearing of 315°. We now North is measured 0°
or 360°, so bearing of 315° is same as North-West 45°.

<em>Note. According to Pythagorean theorem, 45° right triangle with hypotenuse of a has legs equal to a/√2.</em>

<u>How far West Is Musah's final point from the centre?</u>
- 25 + 50/√2 ≈ 60.36 steps
<u>How far North Is Musah's final point from the centre?</u>
- 50 + 50/√2 ≈ 85.36 steps
