What is the answer to m
tigry1 [53]

Answer:

Height of a cell tower is, 30 m

Step-by-step 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;

\frac{h}{40}=\frac{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
