In Quadrant Bearing, how is a 45-degree angle measured?

In Quadrant Bearing, angles are typically measured from the north or south toward the east or west. When measuring a 45-degree angle, you start from the north direction and move towards the east.

A 45-degree angle measured from north towards east is denoted as N45E. This means you are moving 45 degrees in a clockwise direction from the north towards the east. The notation effectively communicates both the direction and the degree measurement, adhering to the quadrant system utilized in navigation and surveying.

In contrast, the other options indicate different directional bearings that do not align with the specified angle of 45 degrees moving towards the east from the north. As such, N45E is the correct representation for this measurement.
