Question

find the bearing from o to a.
the bearing from o to a is (square^{circ}square).

Explanation:

Step1: Recall bearing definition

Bearing is measured clock - wise from the north direction.

Step2: Calculate the bearing

Since the angle is measured from the east direction as $71^{\circ}$, the bearing from $O$ to $A$ is $90^{\circ}-71^{\circ}=19^{\circ}$ east of north, which is written as $N19^{\circ}E$ or simply $19^{\circ}$ in the three - digit bearing convention.

Answer:

$019$
