Question

The maximum slope of a wheelchair ramp is 1:12. For a wheelchair ramp made with these specifications, what angle does the ramp make with the ground? Round your answer to the nearest hundredth.

Answer 1

tan(Θ) = 1 / 12

Answer 2

Since the angle is what needs to be found, the formula should be an inverse one. So the equation should be tan^-1(1/12). Which will give the answer 4.76.
