The latitude and departure of a line AB are + 78 m and – 45.1 m, respectively. The whole circle bearing of the line AB is:
The reduced bearing of a 10 m long line is N30 °E. The departure of the line is
An instrument was setup at P and the angle of depression to a vane 2m above the foot of the staff held at Q was 5° 36’. The horizontal distance between P & Q was known to be 3000 m. Given the staff reading on a benchmark of elevation 436.000 was 2.865m, the R.L of the staff station Q is
