Answer: 24.99 ft

Explanation:

1. You can find the angle A as following:


A=arctan((5)/(8))\\A=32\°

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


tan(A)=(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)=(x)/(40)\\x=40*tan(32\°)\\x=24.99
