Answer

40^\circ$.

Alright Chimuka — let's do this.

Here's the solution for the bearing problem:

a) Calculate the bearing of B from A

Step 1: Find the angles in $\triangle OAB$ . Given that $OB = AB$ , $\triangle OAB$ is an isosceles triangle. The angles opposite the equal sides are equal, so $\angle OAB = \angle AOB$ . The sum of angles in a triangle is $180^\circ$ . We are given $\angle ABO = 40^\circ$ . $\angle OAB + \angle AOB + \angle ABO = 180^\circ$ Since $\angle OAB = \angle AOB$ , let $x = \angle OAB$ .
