The problem is solved by applying the **Pythagorean **Theorem to the right-angled triangle formed by the ladder, the ground, and the wall. The height of the ladder against the wall is found to be approximately 13.23 feet. ;
The ladder touches the wall approximately 13.08 feet above the ground. ;
Using the Pythagorean Theorem, the height at which the ladder touches the wall is found to be approximately 13.07 feet. This is calculated by rearranging the theorem to solve for the height in a right triangle formed by the ladder, the wall, and the ground. The ladder's length and the distance from the wall are used in the calculation to arrive at this height.
