1. The problem is to express a direction or angle in terms of a true bearing in a simple way.
2. A true bearing is the angle measured clockwise from the north direction to the line connecting two points.
3. The formula to convert an angle to a true bearing depends on the quadrant, but generally, true bearing $\theta$ is measured clockwise from north, so:
$$\text{True Bearing} = \theta \text{ degrees clockwise from north}$$
4. Important rules:
- Bearings are always between 0° and 360°.
- North is 0° or 360°, east is 90°, south is 180°, and west is 270°.
5. To express any angle as a true bearing, if you have an angle $\alpha$ measured from the east or another reference, convert it by measuring clockwise from north.
6. For example, if an angle is $30^\circ$ east of north, the true bearing is simply $30^\circ$.
7. If an angle is $45^\circ$ south of west, the true bearing is $270^\circ + 45^\circ = 315^\circ$.
8. In simple terms, always start at north (0°) and measure clockwise to the direction.
Final answer: Express the direction as an angle between 0° and 360° measured clockwise from north, which is the true bearing.
