what is the perfect angle for the back rest of your chair?

180
50
135
90

Correct Answer

A. 90

Explanation

A 90-degree angle is considered the perfect angle for the backrest of a chair because it provides optimal support and comfort for the person sitting. This angle helps maintain proper posture by keeping the spine aligned and reducing strain on the back muscles. It allows for a natural curve in the lower back, promoting good spinal alignment and reducing the risk of back pain or discomfort. Additionally, a 90-degree angle ensures that the weight is evenly distributed on the chair, preventing any unnecessary pressure points or discomfort.

To the closest decimal what is the optimal percentage of oxygen in the workspace atmosphere?

45%
10%
19.75%
20.95%

Correct Answer

A. 20.95%

Explanation

The optimal percentage of oxygen in the workspace atmosphere is 20.95%. This percentage is important as it ensures that there is enough oxygen for individuals to breathe and function properly. Oxygen is necessary for the body to carry out essential functions, and a lower percentage can lead to hypoxia, which can cause dizziness, confusion, and even loss of consciousness. Therefore, maintaining the optimal percentage of oxygen is crucial for the well-being and safety of individuals in the workspace.
