Atree casts a shadow that is about 10 ft long. javier, who is about 5 ft tall, is standing near the tree. javier’s shadow is about 4 ft long. what is the estimated height, t, of the tree?
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

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
