Q1:

The latitude of a traverse leg is obtained by multiplying its length by

A tangent of its reduced bearing

B sign of its reduced bearing

C cosine of its reduced bearing

D cosecant of its reduced bearing.

ANS:C - cosine of its reduced bearing

Latitude = L*cos(angle), as the angle of bearing is taken with reference to the North, hence L*Cos is the latitude and L*Sin(angle) is the departure. Latitude =L cos.
Departure = Lsin. Lcosθ is the right Answer as the angle is taken with respect to North.
