If you know how to work out the distance to the object, you can now work out its height.
For example, if you measure the vertical angle of the object to be 35°
and you have already calculated that it is 1000 meters away, then:
tan(35°)
= ^{opposite}/_{adjacent} =^{ (height)}/_{1000}
height = (1000 x tan 35°) 
Measuring the height of an object using trigonometry
Using this equation, we can work out the height of these objects if we have the angle.
ANGLE
= 45^{o} TAN 45^{o} = 1
Therefore:
HEIGHT = (1000x1) =1000m 
ANGLE
= 70^{o} TAN 70^{o} = 2.747
Therefore:
HEIGHT = (1000 x 2.747) = 2747m 
ANGLE
= 10^{o} TAN 10^{o} = 0.176
Therefore:
HEIGHT = (1000 x 0.176) = 176m
