Answer:
The ramp must cover a horizontal distance of approximately 19.081 feet.
Step-by-step explanation:
Given the vertical distance (), 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)
If we know that and , then the horizontal distance covered by this ramp is:
The ramp must cover a horizontal distance of approximately 19.081 feet.
