[@erashmam25]

RL is a vertical distance between a survey point and the datum surface.

[@erashmam25]

Measure from Mean sea level or from temporary imaginary datum

[@pmwmechanics3038]

Why not to take first angle negative ? For calculation of horizontal distance

[@erashmam25]

Signs indicates above and below horizontal axis . And que is to find horizontal distance from A to B not BM to B

[@erashmam25]

First draw karo staff, tripod stand and angle given data se then formula uske according aa jayega.
When line of sight horizontal
D = (f/i)S + (f+d)
For line of sight inclined, staff vertical
D = (f/i) × S² cosθ + ( f+d)cosθ
1) for +ve angle
V = D tan θ
RL of staff = RL of instrument axis + V - h
2) for -ve angle
RL of staff station = RL of instrument axis - V - h
