By law, a wheelchair service ramp may be inclined no more than 4.76. if the base of a ramp begins 15 feet from the base of a public building, which equation could be used to determine the maximum height, h, of the
For this case we can model the problem as a rectangle triangle. We have an angle and the base of the triangle. To find the height we use the following trigonometric relationship: tan (x) = C.O / C.A Where, x: angle C.O: opposite leg C.A: adjacent leg Substituting values we have: tan (4.76) = h / 15 Clearing h: h = 15 * tan (4.76) Answer: An equation that could be used to determine the maximum height, h, is: h = 15 * tan (4.76)
