Question

For safety, what angle should be created when the ladder is against a building?

1) 30 degrees
2) 45 degrees
3) 60 degrees
4) 90 degrees

Answer 1

The ladder should be placed at a 75-degree angle from the ground for safety, which corresponds with the 4:1 ratio but is not one of the offered choices.

Step-by-step explanation:

For safety, the angle created when a ladder is against a building should be at 75 degrees from the ground, which means the ladder is leaning at a 15-degree angle from the vertical. The ladder should be placed at a 75-degree angle from the ground for safety, which corresponds with the 4:1 ratio but is not one of the offered choices. This angle is not one of the given options; however, the commonly recommended angle for ladder safety is that the ladder's foot should be 1 foot away from the wall for every 4 feet of height to the point where the ladder contacts the wall (4:1 ratio).

This results in an approximate angle of 75 degrees. It's important to note that none of the answer choices matches this recommendation. The closest to the recommended angle is 60 degrees; however, it is still not the ideal angle for ladder safety as per the guidelines.
