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

Simply rearrange the terms and simplify.
Subtracting 4x from both sides, we have:
-11y=-4x-6
Dividing by -11, we have:
This is in the proper form, so this is our final equation.
