Today - Introduction to Trigonometry

Q. I am using a wheelchair and need a ramp so I can access my home independently. What should the slope of the ramp be?

A. The Alberta Building Code states that the slope of a ramp should not exceed 1: 12. That is, for every inch of rise there should be at least 12 inches (or 1 foot) of run. Source

If the steps are 18 inches high, how far does the ramp have to come out from the steps, and how long is the ramp?
