Explanation:

Suppose AB is the 3- foot high access ramp that ends at point C 20 feet along the ground and

theta is the angle of depression from the start of 3 foot high ramp at point A

Now, in ∆ ABC

m<ACB= theta ( alternate interior angle)

Therefore,

$\tan(theta) = (AB)/(BC)$

$\tan(theta) = (3)/(20)$

(theta) = tan⁻¹(3/20)

= 8.5°
