To convert azimuth directions between 090° and 180° to quadrant bearings, follow these steps:
1. Start by determining the quadrant in which the azimuth falls. In this case, the azimuth is between 090° and 180°, which means it falls in the Southeast quadrant.
2. Subtract 90° from the azimuth to obtain the angle within the quadrant. For example, if the azimuth is 120°, subtracting 90° gives us 30°.
3. Add the appropriate quadrant designation to the angle obtained in step 2. Since the azimuth falls in the Southeast quadrant, the quadrant designation is "SE." Therefore, the quadrant bearing would be SE 30°.
4. If the angle obtained in step 2 is a multiple of 10°, you can express it as a whole number without the degree symbol. For example, if the angle obtained is 100°, the quadrant bearing would be SE 10.
5. If the angle obtained in step 2 is not a multiple of 10°, express it as a decimal. For example, if the angle obtained is 115°, the quadrant bearing would be SE 11.5°.
By following these steps, you can accurately convert azimuth directions between 090° and 180° to quadrant bearings.
