the angle of depression of the ramp is 8.5 degrees and the right option is C. 8.5 degrees.

What is angle of depression?

Angle of depression is the angle formed by the line of sight and the horizontal plane for an object below the horizontal.

To calculate the angle of depression, we use the formula below.

Formula:

  • tan∅ = x/y.............. Equation 1

Where:

  • ∅ = angle of depression
  • x = Height of the ramp
  • y = distance of the ramp from where its ends

From the question,

Given:

  • x = 12 feet
  • y = 80 feet

Substitute these values into equation 1

  • tan∅ = 12/80
  • tan∅ = 0.15
  • ∅ = tan⁻¹(0.15)
  • ∅ = 8.5 degree

Hence, the angle of depression of the ramp is 8.5 degrees and the right option is C. 8.5 degrees.
