Geometry
Directions: The Americans with Disabilities Act sets strict
standards for handicapped accessible ramps. The slope must
not be more than 1 inch of rise for every 12 inches of run. Any
slope that is steeper is considered too dangerous.
If the courthouse is building an entrance ramp to go up a
staircase 4’ 3”, what is the minimum length for the ramp to stay
within the ADA guidelines? What is the steepest possible angle
the ramp will create? What horizontal distance is covered by
the ramp?
First create a neat sketch and label all the parts. When finding the
missing lengths and angles, make sure you include an explanation
with necessary computations, sketches, formulas, and notes.
