Welcome back Abiodun😍😍😍 — missed you this week.
Here's how to solve this bearing problem:
First, let's determine the angle ∠CAB in the triangle formed by cities A, B, and C.
- The bearing of B from A is 150∘.
- The bearing of A from C is 015∘. This means the angle from the North line at C, clockwise to CA, is 15∘.
- Since the North lines at A and C are parallel, the interior angle between the line CA and the North line at A (measured counter-clockwise from North) is $180^\circ - 15^\circ = 16
