Question

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
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?
