You're building a 12 foot ramp to the entrance of a building 3 feet above the ground. The ADA regulations require the incline of the ramp to be no more than 5 degrees. What is the degree measure of your angle of elevation? Will it fit the requirements? If not, can you think of a way to make it work. Never mind.
