Answer:

The flagpole is 40 feet tall.

Step-by-step explanation:

So, we are looking for the height of the flagpole. Let h represent this height.

Boy - 5 feet in height and casts a 20-foot shadow

Flag pole - h feet in height and casts a 160-foot shadow

The relationship looks something like this:

5 : 20 :: h : 160

or

[tex]\frac{5}{20} =\frac{h}{160}[/tex]

Now, we can cross multiply to find h!

[tex]20h=800\\h=40[/tex]

So, the flagpole is 40 feet tall
