Question 258269: A ramp is used to make wheelchair access easy. The maximum incline recommended is the ratio 1:12. That is, for each meter in height, the ramp
extends 12 meters in length. Estimate the measure of the angle that this ramp
makes with the level ground.

Applying trigonometry, we know that
Let x = angle
then
tan(x) = opposite/adjacent
.
tan(x) = 1/12
x = tan^-1(1/12)
x = arctan(1/12)
x = 4.76 degrees
