According to the guidelines set by the ADA, Wheelchair ramps should be built at an angle of no more than 4.8 degrees. If a contractor is designing a wheelchair ramp for a doorway that is 5 feet above ground level, What equation could be used to determine the length of the shortest possible ramp to reach the doorway?

sin(theta) = a / c sin(4.8)=5/x x=sin(4.8)/5...................................................................................................................................................................................................

sin(theta) = a / c sin(4.8)=5/x x=5/sin(4.8)..................................................................................................................................................................................................
