Assuming you mean "foot of the ladder": Sqrt(144 - 81) ie sqrt 63 = 7 feet 11¼ inches.
If you mean what you wrote then zero distance!
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.
The proper distance of a ladder from a wall can be determined using the 4-to-1 rule: for every four feet of height you want to reach, the base of the ladder should be one foot away from the wall. This means if the top of the ladder is 12 feet high, it should be placed 3 feet away from the wall. This positioning helps ensure stability and safety while using the ladder. Always make sure the ladder is on a firm, level surface and positioned securely.
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
Using Pythagoras' theorem the length of the ladder is 20.248 feet
To determine the minimal length of a ladder needed to reach a landing nine feet above the adjacent floor, we can use the Pythagorean theorem. Assuming the ladder is positioned at a safe angle (typically around 75 degrees), the minimal length can be calculated. For a height of 9 feet, a ladder length of approximately 10.2 feet would be required when factoring in the angle for safe use. Always ensure the ladder is placed securely and follows safety guidelines.
13 feet
10,000 m
62+82=36+64=100 and the squared route of 100 is 10
The slope is 4 (no units), and the ladder is 16.492 feet long. (rounded)
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.
