A contractor is building a wheelchair accessibility ramp (see figure) for a business. Using your knowledge of right-triangle trigonometry, help advise him how to create a ramp whose dimensions will meet the specification needed that will allow wheelchair accessibility. Talk about the procedure the contractor will need to follow to find the dimensions of the three sides and the measurements of the three angles. Consider the implications of the Americans with Disabilities Act (ADA) in your discussion and provide an example. Okay, I have most of this done, but I can't move onto the next step of my example problem because I am stuck. The following is my example and as far as I have gone. The following is an example of how the contractor would consider the ADA regulations while building a ramp. If the steps for the business have rise of five inches, the rise would become ten inches. The contractor would be able to figure out the equation in the following way. 10/run=1/20 10x20=200 Can someone give me a little help on the next step? I don't need the whole answer, just a push in the right direction. Thanks!

drav: The problem is saying that the ADA requires a maximum slope of 1/20; in other words, if the height of the obstacle is 1 foot (rise), then the horizontal length of the ramp will be 20 feet (run). Therefore, the length of the sloped ramp (hypotenuse) is SQRT(1^2+20^2). Solve for a 10 inch rise in the same way, where the run would be 10*20=200.
