Question

What is the answer to m

Answer 1

Height of a cell tower is, 30 m

Explanation:

Proportion states that the two fractions or ratios are equal.

As per the given statement:

Let height of a cell tower be h.

Height of a pole = 3m ,

Shadow of a pole = 4 m and

shadow of a cell tower = 36+4 = 40 m

By definition of proportion;

`\frac{\text{Height of a cell tower}}{\text{Shadow of a cell tower}} = \frac{\text{Height of a pole}}{\text{Shadow of a pole}}`

Substitute the given values we get;

`(h)/(40)=(3)/(4)`

by cross multiply we get;

`4h = 120`

Divide both sides by 4 we get;

h = 30 m

Therefore, the height of a cell tower is, 30 m
