Tomas is pushing a box up a ramp that rises one foot for every four feet of horizontal distance. What is the approximate measure of angle x?

This is exactly the way the tangent function operates.

Tangent = opposite / adjacent

Tangent = one foot / four feet

Tangent (angle x) = 1 / 4

Arc Tangent (angle x) =

Arc Tangent (.25) = 14.036 Degrees
