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, FG=34\ m

Angle of inclination of Sun with the vertical is 25°.

Therefore, the angle of inclination of Sun with the horizontal is given as:

\angle G=90-25=65\°

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

\tan (\angle G)=\frac{EF}{FG}\\\tan 65\°=\frac{EF}{34}\\EF=34\times \tan 65\°=72.9\ m\approx 73\ m

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