Solve this problem using the Pythagorean Theorem. An extension ladder with 3 five-foot extensions is leaned against a wall with the base of the ladder 5 feet from the base of the wall. How high on the wall does the top of the ladder sit?

Given :-

An extension ladder with 3 five-foot extensions is leaned against a wall with the base of the ladder 5 feet from the base of the wall.

To find :-

How high on the wall does the top of the ladder sit?

Solution :-

Using Pythagoras Theorem ,

5² = 3² + h²25 = 9 + h ²h² = 25 - 9h ²= 16 h =√16 h = ±4 h = 4
