For proper stability, a ladder should be angled at what degree from the base?

75-degree
60-degree
90-degree
45-degree

The correct answer is: 75-degree

A ladder should be angled at approximately 75 degrees from the ground for proper stability. This angle is recommended as it provides a balance between safety and accessibility. At this angle, the ladder is less likely to slip out from under the user while still allowing sufficient height for the person using it. When a ladder is positioned too steeply or too flat, it can compromise stability. For instance, a 90-degree angle, which would mean the ladder is vertical, can lead to a lack of support at the base and increase the risk of it tipping over. Conversely, a 60-degree angle, while somewhat stable, does not provide enough support for heavier loads and may also feel less secure for the user. An angle of 45 degrees is typically too shallow and could cause the ladder to slide or fall, especially when weight is applied. Maintaining the recommended 75-degree angle helps ensure that the ladder is secure, making it safer for the user to climb and work effectively.
