A wheelchair ramp has a slope of 1/12. Which of the following is the angle of elevation of the ramp to the nearest tenth of a degree?
We know that the slope of the ramp is 1/12. To find the angle of elevation, we need to find the inverse tangent of the slope. This can be calculated using a scientific calculator:
tan^-1(1/12) = 4.76 degrees (rounded to the nearest tenth)
Therefore, the angle of elevation of the ramp is approximately 4.8 degrees.
