Answer:

30

Step-by-step explanation:

Given:

Brian Height = 6 feet

Brian Shadow Height = 4 foot

Flag Shadow Height = 20 foot

Flag Height = Unknown ??

So we can use cross multiplication

6/4 = x/20

6×20/4 = x

6×20 =120

120÷4 = 30

So x= 30, which is the Flag Height

As per linear equation, the  height of the flag pole is 30 feet.
