Assignment:
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.
Provide complete and step by step solution for the question and show calculations and use formulas.
