Question

LT1 10th grade level. How tall I’d the building?

Answer 1

Answer: 99.2 m

Explanation:

Given

The height of the flagpole is 35 m which is situated at 60 m

It is clear that the angle of elevation for the flagpole and building is the same, let say
`\theta`

from the figure, we can write

`\Rightarrow \tan \theta=(35)/(60)=(h)/(170)\\\\\Rightarrow h=170* (35)/(60)\\\\\Rightarrow h=99.166\approx 99.2\ m`

Thus, the height of building is 99.2 m
