If the whole circle bearing of a traverse line is between 270°  to 360° , the signs of latitude and departure are:?

Option 4 : + and - respectively

Concept:

Latitude: Projection of a line on N - S direction called latitude.

Departure: Projection of a line on E – W direction is called Departure.

Latitude (L) is given by  L = l × cos θ

Departure (D) is given by D = l × sin θ

Where θ is angle with North direction, 'l' is the length of the line

Given, 

The whole circle bearing of a traverse line is between 270°  to 360°

In which represents the line is in the 4th Quadrant. 

Latitude is +ve and Departure is -ve.
