3. The Math Behind the Triangle: How Long Is the Ladder?
A ladder forming a right triangle with a wall base of 9 feet and a top height of 12 feet follows the classic Pythagorean theorem: a² + b² = c². Here, a = 9, b = 12, and c is the ladder’s length.
Calculating: 9² = 81, 12² = 144.
Adding: 81 + 144 =
