A ramp was built by the loading dock. The height of the loading platform is 4 ft. Determine the length of...?
the ramp if it makes a 32 degrees angle with the ground?
You are setting up a 90 degree angle. Let the length of the ramp be x.
Since you know the height of the loading dock to be 4 and the degree measure (32) of the ground and the ramp (hypotenuse) you need to use the sine function which is opposite over hypotenuse. Set it up this way:
sin 32= 4/x (opp/hyp)
find the sine of 32 on your calculator: .551427
.551427 =4/x
cross mult and you have .551427x = 4
Divide 4 by .551427 and you should get approx 7.25 feet
