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)
