GEOMETRY! The diagram shows 5 ft student standing near a tree. The shadow of the student and the shadow of the tree end at point

yuradex [85]

Answer: 24.99 ft

Step-by-step explanation:

1. You can find the angle A as following:

$A=arctan(\frac{5}{8})\\A=32\°$

2. Now, you can calculate the height of the tree as following:

$tan(A)=\frac{opposite}{adjacent}$

Where:

A=32°

opposite=x

adjacent=40

3. When you substitute values and solve for x, you obtain that the height of the tree in feet is:

$tan(A)=\frac{x}{40}\\x=40*tan(32\°)\\x=24.99$
