Answer:

1.13 feet

Explanation:

We know that the sine relation is ...

Sin = Opposite/Hypotenuse

so the length (L) of the ramp surface will be ...

sin(angle) = 2/L

L = 2/sin(angle)

For 18°, the ramp length will be about ...

L = 2/sin(18°) ≈ 6.472 . . . . feet

For 22°, the ramp length will be about ...

L = 2/sin(22°) ≈ 5.339 . . . . feet

The difference in lengths is about ...

6.472 -5.339 = 1.133 ≈ 1.13 . . . . feet
