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.
assuming the wall and ground make a 90 degree angle with one another, Pythagorean's Theorem states the ladder will go 8 feet up the wall.
The best tip I've come to is that for every four feet of height you have to climb, move the base one foot away from the wall. Better still is to have someone foot the ladder, or to fasten the ladder with a rope, preferably near the top of the ladder to avoid the ladder sliding sideways.
12 feet. It is actually pretty easy, if you remember that a 3x4x5 triangle is always a right angle. divide by 3 and you have the 3 and 5 all you need is the four multiplied by 3.
