Answer:

Height of the building = 50.8 ft

Explanation:

A person and a building are casting the shadows at the same time of the day.

Triangles formed by the person and his shadow and the building and its shadow will be similar.

Therefore, corresponding sides of the similar triangles will be proportional.


(x)/(28)=(5.8)/(3.2)

x =
(5.8* 28)/(3.2)

x = 50.75

x ≈ 50.8 ft
