Question

The figure shows a child estimating the height of a tree by looking at the topof the tree with a mirror. Assuming that both the child and the tree form rightangles with the ground, which of the following proportions can be used toestimate the height of the tree?

Answer 1

Given:-

The figure shows a child estimating the height of a tree by looking at the top of the tree with a mirror. Assuming that both the child and the tree form right angles with the ground.

To find:-

which of the following proportions can be used to estimate the height of the tree?

Now we use the proportion as,

So the propotion formula here is,

`(a)/(d)=(b)/(c)`

So now we substitute the known values. so we get,

`(h)/(4)=(12)/(5)`

So the required answer is OPTION D.
