ECZ 2021 · GCE Paper 1 — Bearings
In the diagram, A, B and C are points on level ground. The bearing of B from A is 032°, angle ACB = 100° and AC = BC. Find the bearing of C from B.
- A. 172°
- B. 212°
- C. 152°
- D. 188°
Verified working — step 1
The bearing of A from B is the back bearing of 032°, which is 212°. Triangle ABC is isosceles with base angles 40°, so angle ABC = 40°. Turning from BA towards BC reduces the bearing: 212° − 40° = …The full step-by-step working and final answer are included with Premium — checked against ECZ marking standards.
