What is the correct angle for a ladder leaning against a wall?

• A. 60 degrees
• B. 75 degrees
• C. 80 degrees
• D. 90 degrees

Answer: (B)

The correct angle for a ladder leaning against a wall is 75 degrees. This angle is considered optimal for safety and stability when using a ladder. At this angle, the ladder is less likely to slip or fall over, while providing sufficient reach to the intended height. Maintaining a 75-degree angle helps distribute the weight effectively. A ladder positioned at this angle is more comfortable for climbing and descending, reducing strain on the user. It is also important to ensure that the base of the ladder is placed far enough away from the wall, typically a distance about one-fourth the height of the ladder, to achieve this angle. While alternatives such as 60 degrees, 80 degrees, and 90 degrees may seem valid, they do not provide the same level of safety and practicality. For instance, a 60-degree angle could make the ladder feel less secure, while an 80-degree angle might be too steep and increase the risk of slipping. A 90-degree angle is vertical and is not a practical position for a leaning ladder. Thus, the 75-degree angle is the recognized standard for safe ladder usage against a wall.
