The bearing of a point X from a point Y is 074°. What is the bearing of Y from X?
- A. 106°
- B. 146°
- C. 164°
- D. 254°
Correct Answer: D. 254°
Explanation
< YXS = 74° (alternate angles, N\(_1\) S\(_1\) // N\(_2\) S\(_2\))
N\(_2\) E\(_2\) S\(_2\) = 180°
\(\therefore\) Bearing of Y from X = 180° + 74°
= 254°
