Question

If the slope of a wheelchair ramp is 1/11 then what is the angle of inclination to the nearest tenth of a degree?

Answer 1

The answer is 4.8 degrees

Answer 2

4.8 degrees to the nearest tenth.

Explanation:

The slope = rise / run = opposite side / adjacent side.

So the angle of inclination is the angle whose tangent is 1/12.

To the nearest tenth of a degree it is 4.8 degrees.
