The length of the ramp is 96.5
Given the following parameters from the question
The vertical rise of the ramp = 8 inches
The angle of elevation = 4.76°.
Required
length of the ramp
Using the SOH CAH TOA identity;
tan theta = opp/hyp
sin4.76 = 8/H
H = 8/sin4.76
H = 8/0.0829
H = 96.5
Hence the length of the ramp is 96.5
