The bearing from O to A is the measure of the angle between the North and The arrow of A
Since the North is perpendicular to the East, then
The angle between N and E is 90 degrees
Then subtract 75 degrees from 90 degrees to find the angle between the North and the arrow of A
[tex]\begin{gathered} B=90^{\circ}-75^{\circ} \\ B=015^{\circ} \end{gathered}[/tex]
The bearing from O to A is 015 degrees
Note that we measure the bearing from North to the position clockwise
