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.
It depends on the size of the bricks and their orientation.

he should bud the ladder so it wouldn't be able to reach

15 meters, or less, depending on the angle.

that depends on the hieght of the building.

The diagonal is 14.142 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.

Hypotenuse = 20/sin580 = 23.58356807 Length of ladder: rounded to 23.584 feet
Twenty divided by the cosine of 32 gives you 23.584 ft
