The height of the ramp from the ground is 9.3 feet to the nearest tenth of a feet.

Angle of elevation and depression

The angle of elevation is an acute angle located at the base of the triangle.

From the given question, we have the following parameters

Length of the ramp = 22inches

Angle of elevation  = 25 degrees

Required

Height of the ramp

Using the SOH CAH TOA identity:

sin 25 = opp/hyp
sin 25 = H/22
H = 22 sin 25
H = 9.3 inches

Hence the height of the ramp from the ground is 9.3 feet to the nearest tenth of a feet.
