a lamp post that is 8 feet high casts a shadow 5 feet long. how tall is the person standing beside the lamp post if his shadow is 3.5 feet long
Answered by Steve
the ratio of height to shadow length is the same, so

h/3.5 = 8/5
I imagine you can solve that for h.

When a 4-foot high stick is held perpendicular to the ground 12 feet away from a lamppost, it casts a 6-foot-high shadow. When the same stick is x feet away from the lamppost, it casts a 3 foot shadow. What is the value of x?
