Question

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

Answer 1

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)
