    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

    \frac{5}{20} =\frac{h}{160}

    Now, we can cross multiply to find h!

    20h=800\\h=40

    So, the flagpole is 40 feet tall
