**How To Calculate The Height Of Any Buildings And An Objects Using With Theodolite**

Let us now calculate the height of the building using a theodolite as shown below.

First, you have to level the theodolite in the vertical axis and set the angle to 0Â° in the horizontal axis i.e. shown as a dotted line. You have to measure the distance (L ) of the building from the theodolite station point as shown in the drawing.

Bisect the top edge corner of the building using the theodolite and note down the value of angleÂ Î¸1. Similarly, bisect the bottom edge corner of the building and write down the value of angle Î¸2.

Let us redraw the above triangles for the calculation purpose with the measured angle values.

Let us name triangle 1 as ABC, where A is the theodolite station point.

__Triangle ABC :__

__Given data:__

AngleÂ Î¸1 = 34Â° 7′

Length AB = L = 72m.

From trigonometry,

Tan Î¸1

= opposite sideÂ Ã· adjacent side.

= side BC Ã· side AB

Tan 34Â° 7′

= h1 Ã· 72m.

h1 =Â tan 34Â° 7′Â Ã— 72m.

= 0.67747Â Ã— 72m

=Â **48.778m.**

Let us name triangle 2 as ABD, where A is the theodolite station point.

__Given data__:

__Given data__

AngleÂ Î¸2 = 1Â° 12′

Length AB = L = 72m.

From trigonometry,

Tan Î¸2 =

opposite sideÂ Ã· adjacent side.

= side BD Ã· side AB

Tan 1Â° 12′

= h2 Ã· 72m.

h2 =Â tan 1Â° 12′Â Ã— 72m.

= 0.02094 Ã— 72m

=Â **1.508m.**

**Now, the height of building**

H = h1 + h2

= 48.778m. + 1.508m.

=**Â 50.286m.**
