### Converting Azimuth to Bearing

**Question 11:** Convert the following azimuth angles to bearings.

**a.** 120° Az  
**b.** 315° Az  
**c.** 245° Az

**Explanation:**

- **Azimuth:** The azimuth is a measurement in degrees (°) used in navigation to describe the direction of an object. It is measured clockwise from the North. 
- **Bearing:** Bearing is a direction or path along a compass, which also uses degrees but is expressed differently. Bearings are typically expressed in terms of North, East, South, and West (e.g., N45°E).

To convert azimuth to bearing:
1. Determine which quadrant the azimuth angle lies in (NE, SE, SW, NW).
2. Subtract or add the angle from 90°, 180°, 270°, or 360° respectively to convert to the bearing format.

In this context, the specifics for the given examples are:
- **120° Azimuth:** This is in the Southeast quadrant. Bearing would be S60°E.
- **315° Azimuth:** This is in the Northwest quadrant. Bearing would be N45°W.
- **245° Azimuth:** This is in the Southwest quadrant. Bearing would be S65°W.

Refer to diagrams and quadrant charts for visual understanding. 

Note: No diagrams or graphs are included in the original text, thus not explained.
