Answer:
22.5feet
Explanations:
The sketch of the diagram that represents the statement is given as:
In order to determine the height "H" of the building, we will use the similarity theorem of the triangle as shown:
![(H)/(30)=(6)/(8)](https://img.qammunity.org/2023/formulas/mathematics/college/cxmt8caqe22brd0mkwtm1baiqwre9od76u.png)
Cross multiply
![\begin{gathered} 6*30=8* H \\ 180=8H \\ H=(180)/(8) \\ H=22.5feet \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/fkhsbigp9iy8lesgqy3jr3izfef4w1t8oz.png)
Hence the height of the building is 22.5feet
