A flag pole casts a 5 foot shadow while a nearby sign post casts a l 1/4 foot shadow. Find the height of the flagpole if the sign post is 4 feet high.

16 ft

Step-by-step explanation:

if the signpost is 4 ft and the shadow is 1.25 feet, the ratio of the shadow to post is 1.25:4 or 5/16

If the flagpole makes a 5 ft shadow, the equation for the height is 5/(5/16)

5/(5/16) = 5/0.3125 = 16
