7/16 is the proper answer
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](https://tex.z-dn.net/?f=FG%3D34%5C%20m)
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\°](https://tex.z-dn.net/?f=%5Cangle%20G%3D90-25%3D65%5C%C2%B0)
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](https://tex.z-dn.net/?f=%5Ctan%20%28%5Cangle%20G%29%3D%5Cfrac%7BEF%7D%7BFG%7D%5C%5C%5Ctan%2065%5C%C2%B0%3D%5Cfrac%7BEF%7D%7B34%7D%5C%5CEF%3D34%5Ctimes%20%5Ctan%2065%5C%C2%B0%3D72.9%5C%20m%5Capprox%2073%5C%20m)
Therefore, the height of the building is approximately 73 m.
