Answer: 
Step-by-step explanation:
Let 'x' be the height of tree.
The length of shadow of a tree = 14 m
The length of shadow of a person =4 m
The height of person = 1.8 m
<em>Since both man and tree are standing vertical to the ground.
</em>
<em>Assume the formation of shadow is happening at the same time then the angle that the sun hits the earth making shadows of both person and tree will be equal.</em>
By direct proportion , we have
