Asix foot man is standing 10 feet away from a 20 foot lamppost. what is the length of his shadow?

4.29 feet ( approx )

Step-by-step explanation:

Let x be the length of the shadow of man,

Given,

The height of the man = 6 feet,

The height of the lamppost = 20 foot,

Distance of the man from the lampost = 10 feet,

By making the diagram,

We found two similar triangles in which first triangle having sides 6 and x,

Second triangle having sides 20 and x + 10,

∵ The corresponding sides of similar triangle are in same proportion,

Hence, the length of the shadow is approximately 4.29 feet.
