Need help ASAP. The diagram shows 5ft student standing near a tree. The shadow of the student and the shadow of the tree at endp

inna [77]

Answer:

The height of the tree = 25 feet

Step-by-step explanation:

From the given diagram : EF = 5 feet, FA = 8 feet, CA = 40 feet

∠AFE = 90° and ∠ACB = 90°

To find : CB, the height of the tree.

Solution : In ΔAEF and ΔAB C

∠AFE = ∠ACB = 90°

∠A is common angle.

So, By AA postulate of similarity of triangle, ΔAEF ~ ΔABC

Now, sides of similar triangles are proportional to each other

$\implies\frac{FA}{CA}=\frac{EF}{CB}\\\\\implies \frac{8}{40}=\frac{5}{CB}\\\\\implies CB=\frac{40\times 5}{8}\\\\\implies CB=25$

Hence, The height of the tree = 25 feet
