A man 6 feet tall stands 12 feet away from a 16 foot tall lamp post. How long is the shadow of the man that is cast by the light of the lamp post?

The shadow overlaps, right? We can't answer this question. Too many components are missing.

Suppose the shadow x feet
Then 16 : 6 = (12 + x) : x
16x = 6 (12 + x)
16x = 72 + 6x
10x = 72
x = 7,2 feet
