Regard the ladder as the hypotenuse and the distance from the wall as one leg of a right angled triangle.
Then, 262 = 102 + H2 : where H is the height reached up the wall by the ladder.
H2 = 676 - 100 = 576 : H = √576 = 24

A 12-foot extension ladder, when fully extended, reaches a maximum height of approximately 12 feet. However, the actual reach can be affected by the angle at which the ladder is placed against a wall or surface. Generally, to ensure safety and stability, it is recommended to set the ladder at a proper angle, which might reduce the vertical reach slightly.
he should bud the ladder so it wouldn't be able to reach

You lean a ladder that reaches to the top of a house. You want to measure how tall the house is, but you can't measure it. The base of the ladder is 6 feet away from the house and the ladder is 26 feet long. How tall is the house?
13 feet
To safely access the roof using a ladder extension, make sure the ladder is long enough to reach the roof and is securely placed on a stable surface. Extend the ladder at least 3 feet above the roof edge for stability. Use proper ladder safety techniques, such as maintaining three points of contact and facing the ladder while climbing. Have someone hold the ladder at the base for added stability.
15 meters, or less, depending on the angle.
