Explanation

Given:

The horizontal distance from Ali to the base of the tree = 10 m.
The vertical distance from Ali’s eyes to his feet = 1.5 m.
The hypotenuse from Ali’s eyes to the top of the tree = 15 m.

Step-by-step solution:

Let the height of the tree be $h$ . Since Ali’s eyes are 1.5 m above the ground, the height of the tree above Ali’s eyes is $h - 1.5$ .
Using the Pythagorean theorem in the triangle formed:
Simplify:
Subtract 100 from both sides:
Take the square root of both sides:
$h - 1.5 = sqrt{125}$ $h - 1.5 \approx 11.18$
Add 1.5 to both sides to get $h$ :

Square root of 48
