The proper angle for setting up an extension ladder is about 75 degrees. This angle provides stability and safety while climbing.
The recommended angle for setting up an extension ladder safely is about 75 degrees.
About 15 degrees. Many, if not most, extension ladders today have a sticker on the side that shows a line that should be parallel to the ground when the ladder is at the proper safe angle.

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)
You may set the correct distance by trying different angles so that you feel confortable when climbing the ladder. Approximately between 80 to 130 cm. But it is the correct angle that can tell you the adequate distance from the wall. Only by climbing a ladder you know it. I advise you to put a piece of rubber under the ladder so that it can't slip.

The safest angle for a ladder is about 75 degrees from the ground. This angle helps prevent accidents and ensures stability while using the ladder.

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.
Well it depends on what ladder it is some are safe some are not
The angle of elevation of the ladder leaning against the wall is approximately 48.59 degrees.
The ladder is set at a steeper angle
