1: To be ADA compliant, wheelchair ramps require no more than a 4.8-degree slope for the ramp. How long in feet would a ramp need to be to reach a porch that is 36 inches above the ground.

2: If ramps can be no longer than 30 feet. Can just one ramp be built to reach the porch or would a landing and another ramp be needed to stay ADA compliant? Show and explain your work using mathematical language from this course.

Answer 1

The length of the ramp is about 35 feet.

What are trigonometric ratios?

The trigonometric ratios are sine, cosine and tangent. These trigonometric ratios are used to solve the right angled triangle. A right angled triangle is one that has one of its angles as 90 degrees.

Now;

length of the ramp = 36/sin 4.8 degrees = 430 inches

If the ramps can not be more than 30 feet, just one ramp can not be used. This is because, the length of the ramp is 35 feet hence we need to build another ramp be needed to stay ADA compliant.
