Answer 1

Explanation:

We are dealing with similarity here. Set up a proportion:

`(x)/(36) =(47)/(9.4)`

The fraction on the left is the information regarding the building, and the fraction on the right is the information regardin the flagpole. The heights of both are on the top and the lengths of the shadows are on the bottom. Cross multiply to solve:

9.4x = 1692 so

x = 180
