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

Dmitry_Shevchenko [17]

Answer:

25 ft

Step-by-step explanation:

The 2 triangles are similar hence the ratios of corresponding sides are equal, that is

$\frac{x}{5}$ = $\frac{40}{8}$ = 5

multiply both sides by 5

x = 5 × 5 = 25

The height of the tree is 25 ft
