ECZ 2013 · O-Level Paper 1 — Bearings
In the diagram, C is due East of A and due North of B. Angle BAC is 50 degrees. Find the bearing of A from B.
- A. 040 degrees
- B. 220 degrees
- C. 140 degrees
- D. 320 degrees
Verified working — step 1
Triangle ABC is right-angled at C, so angle ABC = 90 - 50 = 40 degrees. From B, C is due North and A lies 40 degrees to the west of that direction, giving a bearing of 360 - 40 = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
