To find the distance from the building where the heel of a 10-meter ladder should be placed to reach a height of 8 meters, we can use the Pythagorean theorem. Let ( d ) be the distance from the building. The equation is ( d^2 + 8^2 = 10^2 ). This simplifies to ( d^2 + 64 = 100 ), resulting in ( d^2 = 36 ), thus ( d = 6 ) meters. Therefore, the heel of the ladder should be placed 6 meters from the building.
It should be placed 2 ft from the wall
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.
For a working height of 12 feet, the ladder should be placed at a base distance of approximately 3 feet away from the wall for every 4 feet of ladder height. This means the base of the ladder should be about 9 feet from the wall. Additionally, ensure that the ladder is on stable ground and that the top is securely positioned against the surface to prevent slipping. Always follow the manufacturer's guidelines for specific ladder types.

It can be any angle that is more than zero degrees and less than 90 degrees. <><><> It will be an ACUTE angle, and if the ladder is placed properly (1 ft out for each 4 ft up) the angle between wall and ladder will be ABOUT 18 degrees.

For a two-storey building, a ladder that is at least 24 feet long is typically recommended. This length provides enough reach to safely access the roof or upper windows, considering the height of each storey is usually around 10 to 12 feet. It's important to ensure the ladder is placed at a proper angle for stability and safety. Always follow local regulations and guidelines when selecting and using a ladder.
