Answer:

(d) 7.9 ft

Explanation:

The geometry of the problem can be represented by a right triangle whose hypotenuse is the ramp, and the side opposite the given angle is 3 feet. Then the relevant trig relation is ...

Sin = Opposite/Hypotenuse

Solving for Hypotenuse, we find ...

Hypotenuse = Opposite/Sin

ramp length = (3 ft)/sin(22.3°) ≈ 7.9 ft

The ramp is about 7.9 feet long.
