Q. Assume that you need to get a heavy couch into the bed of a pickup truck. You know the bed of the truck is at the height of 1.00 and you require a ramp that makes an angle of 40 with the ground if you are to be able to push the couch.
Utilize the sine function to find out how long of a board you require to use to make a ramp that just reaches the 1.00 high truck beds at a 40 angle to the ground.
