The length of the ramp, which is the hypotenuse of a right triangle, can be found using the formula:
length = horizontal distance / sin(angle)
Plugging in the given values, we get:
length = 14 feet / sin(9º)
Using a calculator, we find:
length ≈ 85.67 feet (rounded to two decimal places)
Therefore, the length of the ramp is approximately 85.67 feet.
