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.
Tan is opposite/adjacent.
Tan=8/6
Tan=simplified to 4/3
So you answer is C.
Hope This Helps and God Bless!
