Answer:
The height of the building is approximately <u>73 m</u>.
Step-by-step explanation:
The triangle EFG is shown below.
Given:
Length of shadow of building is, 
Angle of inclination of Sun with the vertical is 25°.
Therefore, the angle of inclination of Sun with the horizontal is given as:

Now, in triangle EFG as shown below, we use the tangent ratio to determine the height of building EF. Therefore,

Therefore, the height of the building is approximately 73 m.
