Answer:
101.58 in
Step-by-step explanation:
The ramp r is the hypotenuse of a right triangle with the ground and 28 in height being the legs.
The angle of elevation 16° is the angle inside the triangle opposite the 28 in height.
Using the sine ratio in the right triangle, then
sin16° = = ( multiply both sides by r )
r × sin16° = 28 ( divide both sides by sin16° )
r = ≈ 101.58 in

This is a question to use proportions on.
3/4 cups 1 cup
/ =
3 cups x
Cross multiply
3 cups = 3/4x
multiply both sides by 4/3
4=x
Answer: x > 38
