Answer:

Option B) 12.5 ft

Step-by-step explanation:

we know that

A tree casts a shadow that is about 10 ft long

Javier is 5 ft tall and Javier’s shadow is about 4 ft long

using proportion

Find out the estimate height of the tree

Let

x ----> the estimate height of the tree

[tex]\frac{5}{4}=\frac{x}{10}\\\\x=5*10/4\\\\x= 12.5\ ft[/tex]

therefore

The estimate height of the tree is 12.5 ft
