Question

BRAINLIEST! will give BRAINLY! can someone please explain, I don't understand how to do this.

Answer 1

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° = $\frac{opposite}{hypotenuse}$ = $\frac{28}{r}$ ( multiply both sides by r )

r × sin16° = 28 ( divide both sides by sin16° )

r = $\frac{28}{sin16}$ ≈ 101.58 in
