Acarpenter is building a ramp that will extend from the ground to the base of a doorway that is 3 feet above the ground. the ramp will be 20 3/4 feet long. which value is closest to the angle of elevation of the ramp?

The angle of elevation is given by,

∅ =

Step-by-step explanation:

The length ladder is given as 20.75 feet.

The depth of ground is 3 feet below.

The figure formed is that of a right angled triangle.

Let the angle of elevation be ∅.

By trigonometry,

sin(∅) =

Thus, the angle of elevation is given by,

∅ =

the correct answer is x/3+10≥32

hope this !
