A line has a whole-circle bearing of 128°20′. What is the whole-circle bearing of its back bearing?
Correct answer: A. 308°20′
- A. 308°20′
- B. 128°20′
- C. 231°40′
- D. 51°40′
Explanation
The back bearing is obtained by adding 180 degrees when the fore bearing is less than 180 degrees. Thus, 128°20′ plus 180° equals 308°20′.

About Surveying
Surveying covers measurement of distances, angles and elevations, traversing, levelling, contouring, plane table work, theodolites, total stations and basic photogrammetry. It includes error adjustment, coordinate calculations, area and volume determination, and the distinction between accuracy and precision, as well as between temporary and permanent adjustments.
