Respuesta :

Given :

A 136 foot tall cell phone tower casts a 79.9 foot shadow.

To Find :

The shadow length for a nearby 40 foot telephone pole .

Solution :

We know , the ratio of height and shadow , will be same for every object .

Let , length of shadow of pole is x .

So ,

[tex]\dfrac{79.9}{136}=\dfrac{x}{40}\\\\x=\dfrac{79.9\times 40}{136}\ foot\\\\x=23.5\ foot[/tex]

Therefore , the length of shadow of tower is 23.5 foot .

Hence , this is the required solution .

Answer:

x = 40ft/23.5ft

Step-by-step explanation:

[tex]\frac{136ft}{79.9ft}[/tex]    =     [tex]\frac{40ft}{x}[/tex]

136x = 79.9 · 40

136x = 3196

136 ÷ 136 = 3196 ÷ 136

[tex]\frac{136ft}{79.9ft}[/tex]  =  [tex]\frac{40ft}{23.5ft}[/tex]
