The departure of a traverse line is obtained by multiplying its length with the tangent of its reduced bearing.

Agree

Disagree

153.

When the whole circle bearing of a traverse line is between 90? and 180?, then

A.	the latitude is positive and departure is negative	B.	the departure is positive and latitude is negative
C.	both the latitude and departure are positive	D.	both the latitude and departure are negative

154.

The latitude and departure of a traverse line are both positive when the whole circle bearing of the line lies in the

A.	first quadrant	B.	second quadrant
C.	third quadrant	D.	fourth quadrant

155.

When the latitudes and departures are so adjusted that the algebraic sum of the latitudes and departures are equal to zero, the operation is called

A.	balancing the latitude	B.	balancing the departure
C.	balancing the traverse	D.	none of these

156.

When the angular and linear measurements are equally precise in traversing, the balancing of a traverse is done by

A.	transit rule	B.	empirical rule
C.	Bowditch's rule	D.	any one of these

157.

When the angular mesurements of a traverse are more precise than the linear measurements, the balancing of a traverse is done by

A.	transit rule	B.	empirical rule
C.	Bowditch's rule	D.	any one of these

158.

The distance by which the last point of the traverse falls short to coincide with the starting point is called the closing error.
