This is known as trigonometric heighting and is the basis for all height measurement with a total station, its formulae is ...

HB = HA + [ hi - VAB – hr]

HB = HA + ∆HAB = HA + [ hi + VAB + hr]

HB = HA + ∆HAB

HB = HA + ∆HAB = HA + [ hi + VAB – hr]

18.

Inverted target, the right formulae is ...

HB = HA + ∆HAB = HA + [ hi + VAB + hr]

HB = HA + ∆HAB = HA + [ hi - VAB + hr]

HB = HA + ∆HAB = HA + [hr + VAB + hi]

HB = HA + ∆HAB = HA + [ hi + VAB - hr]
