Question

1) When sighted to the same target, what is the geometric relationship between the horizontal angles observed in the direct and reverse faces.  

a) They should differ by 180°

b) They should differ by 90°

c) They should sum to 180°

2) Which of the following includes only direct measurements that are made by a total station?

a) Slope distance, Zenith Angles, X, Y, Z Coordinates

b) Horizontal Distance, Horizontal Angle, and Vertical Distance

c) Slope Distance, Horizontal Angle, and Zenith Angle

Answer 1

Solution

1) When sighted to the same target, what is the geometric relationship between the horizontal angles observed in the direct and reverse faces.  

A. They should differ by 180

As angles measured are forebearing and backbearing which differ by 180 always

2) Which of the following includes only direct measurements that are made by a total station?

C Slope distance , Zenith angle , Horizontal angle

As these are the only direct measured directly by the total station.
