Safe wheelchair ramp specifications require about 4.75° maximum angle to be constructed with the ground. At a particular building, the owner is installing a wheelchair ramp that needs to rise 1 feet off the ground. The owner insists on constructing the angle with the ground at 3°. How much horizontal distance will the ramp cover with these specifications?
Answers: 2
), measured in feet, and the angle of the wheelchair ramp (
), measured in sexagesimal degrees. The horizontal distance needed for the ramp (
), measured in feet, is estimated by the following trigonometrical expression:
(1)
and 
, then the horizontal distance covered by this ramp is:
