13.6 feet
Lean a ladder against a wall. Not too steep . . . Give it a nice angle, for safe climbing. The height is the distance between the ground and the place where it hits the wall. The slant height is the length of the ladder.

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.

To determine the minimum height of a ladder needed to reach the top of the roof, measure the vertical distance from the ground to the top of the roof. This measurement will be the minimum height required for the ladder.
10 feet, and it is at a very dangerous angle.

The angle formed between the ladder and the house is typically a right angle (90 degrees) if the ladder is resting against the wall of the house. This assumes that the base of the ladder is on the ground and the wall is vertical. If the ladder is leaning at an angle, the specific angle would depend on how far the base of the ladder is from the wall and its height against the wall.
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.

Assuming it is a two section ladder then it must therefore have a minimum length of 28 feet.
To find the distance from the base of the wall to the bottom of the ladder, we can use the Pythagorean theorem. The ladder, wall, and ground form a right triangle, with the ladder as the hypotenuse. Given that the ladder is 13 feet and the height of the wall is 12 feet, we can calculate the base distance (x) using the equation (x^2 + 12^2 = 13^2). Solving gives (x^2 + 144 = 169), leading to (x^2 = 25), and thus (x = 5) feet.
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 is not a proportion. There needs to be aroubd a 75 degree angle from the ground to the base. If it is too flat the ladder can slip out from underneath you. If it is too steep you can tip back. There is usually an angle at the bottom of the ladder if that is flat on the ground then that should be the safest angle (75 degrees)
