Latitude

The latitude of a line is its projection on the north-south meridian and is equal to the length of the line times the cosine of its bearing.

Departure 

The departure of a line is its projection on the east-west meridian and is equal to the length of the line times the sine of its bearing.

Latitude = L cos α 

Departure = L sin α 

L = Length of AB

Calculations

N 60° W

So

Latitude = L cos α 

Departure = L sin α 

Latitude = 100 × cos (60°) = + 50m

Departure = -100 × sin 60 = - 86.6m
