a) 8 ft
b) 12.5 ft
c) 15.5 ft
d) 18.5 ft

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

therefore

The estimate height of the tree is 12.5 ft

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
