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.
It is: 24 feet by using Pythagoras' theorem
13.6 feet
You should normally have three rungs(steps) past the surface you are climbing to from the ladder. They are a foot apart on most ladders so 15 feet would be close. Add a foot since you have to angle the ladder appropriately(scope) so 16 feet or longer is safe. A 20 foot extension ladder would be a good choice.
The pitch would be 3.74 4.5 x 12 = 54" rise 54 / 14.42 = 3.74
62+82=36+64=100 and the squared route of 100 is 10

A ladder should extend at least 3 feet beyond the surface it is accessing to ensure stability and prevent the ladder from slipping. This distance provides a secure anchor point for climbing up and down safely.
he should bud the ladder so it wouldn't be able to reach
A roof ladder or an extension ladder can be used for accessing the roof of one's home. One should take precautions when using a roof ladder to ensure safety. One should position the ladder so the bottom of the ladder is away from the wall one foot for every four feet in height it will be raised. The top of the ladder should be extended no more than four feet above the roof line. One should keep their body in the center of the rungs as they climb the ladder.
Feet is the standard measurement of altitude, or vertical distance. Metres, kilometres are used as a standard of horizontal distance. The nautical mile is used for navigational distance. The three seemingly different units of measurement, measure three different things. If a pilot hears a distance in feet, he or she immediately thinks of vertical distance. Metres is immediately related to horizontal distance, and nautical miles to navigational distance. The reason is to stop confusion.
13 feet
No. since the ladder must be on an angle it must have room so that the length of the ladder is equal to the 282 + (distance between bottom of ladder and house)2.
