In Alberta, ramps that are designed for people using mobility devices must meet certain safety requirements. One such requirement is that the angle between the ramp and the horizontal must be less than 4.8 degrees. Explain whether or not the ramp in the picture below is acceptable.
The ramp has a 94.7 degree angle but I'm not sure if there are other calculations I need to do.

Wait do you have the proper steps to that

To determine whether the ramp in the picture is acceptable according to the safety requirement, we need to calculate the angle between the ramp and the horizontal.
In this case, we are given that the ramp has a 94.7-degree angle. However, we need to convert this angle to the angle between the ramp and the horizontal.
To find the angle between the ramp and the horizontal, we subtract the given angle from 90 degrees because the horizontal is perpendicular to the vertical.
Angle between ramp and horizontal = 90 degrees - 94.7 degrees = -4.7 degrees
Now, we have the angle between the ramp and the horizontal as -4.7 degrees. According to the safety requirement stated earlier, the angle between the ramp and the horizontal must be less than 4.8 degrees.
Since -4.7 degrees is less than 4.8 degrees, the ramp in the picture meets the safety requirement for an acceptable ramp design in Alberta.
