In quadrantal bearing system, back bearing of a line may be obtained from its forward bearing, by

adding 180°, if the given bearing is less than 180°

subtracting 180°, if the given bearing, is more than 180°

changing the cardinal points, i.e. substituting N for S and E for W and vice-versa

none of these.

You are right @Nilesh.

Quadrant bearing means taking direction with respect to N-S, E-W.

Durgesh said: 9 years ago

Yes, C is the right answer.

Quadrant bearing is the use of N-S, E-W in identifying the direction. C is the correct answer.

Ye, I agree with Nilesh.

Subtracting 180°, if the given bearing, is more than 180 that right.

It is quadrant bearing system not whole circle so for back bearing we just have to change the quadrant just opposite of given not sub or add 180.

For calculating back bearing BB = FB+-180. I Think A & B are correct. How could C?

BB = FB + or - 180°.
