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.
Well it would be 70% of them because Jack had 100% and 30% minus 100% is 70%
