If your Azimuth is more than 180 degrees, how do you find your Back Azimuth?

To determine the Back Azimuth when your Azimuth is more than 180 degrees, the correct method is to subtract 180 degrees from the given Azimuth. The Back Azimuth is the direction that is exactly opposite your current direction, and for an Azimuth that exceeds 180 degrees, subtracting 180 will effectively provide you with the angle on the opposite side of the compass.

For example, if your Azimuth is 210 degrees, subtracting 180 gives you 30 degrees, which represents the direction directly opposite to 210 degrees. This is a fundamental concept in navigation, ensuring you can orient yourself accurately in relation to your current heading.
