Question

1. the man in this photograph has been working on his laptop for several hours now and is starting to get a headache. whats causing his pain--the stress of the job or the way hes sitting and looking at his screen? remember that osha set the safe viewing angle for computer use at 15 - 20 degrees. can you use your knowledge of how to draw and measure angles to determine the likely cause of this mans headache? answer:

Explanation:

Step1: Observe the man's viewing angle

Use a protractor or angle - measuring tool to measure the angle between the man's line of sight and the vertical of the laptop screen.

Step2: Compare with OSHA standard

If the measured angle is outside the 15 - 20 degrees range, the way he's sitting and looking at the screen could be a cause. If it's within the range, then the stress of the job might be more likely.

Answer:

Measure the viewing angle of the man looking at the laptop screen. If the angle is not within 15 - 20 degrees, the way he's sitting and looking at the screen is likely the cause. If it is within 15 - 20 degrees, the stress of the job may be the cause.
