Question

Every line has two bearings such as fore bearing and back bearing. If fore bearing is less than $180^\circ$, then what will be the back bearing?

• A. Back bearing = Fore bearing - \(180^\circ\)
• B. Back bearing = Fore bearing + \(180^\circ\)
• C. Back bearing = Fore bearing
• D. Back bearing = \(180^\circ\) - Fore bearing

Hint:

Back bearing = fore bearing \(\pm 180^\circ\), depending on value.

Answer 1

The Correct Option is B

If fore bearing is less than \(180^\circ\), back bearing is found by adding \(180^\circ\).
