Part A Suppose that you need to get a heavy couch into the bed of a pickup truck. (Figure 2) You know the bed of the truck is at a
height of 1.00 m and you need a ramp that makes an angle of 40° with the ground if you are to be able to push the couch.
Use the sine function to determine how long of a board you need to use to make a ramp that just reaches the 1.00-m high
truck bed at a 40° angle to the ground
Express your answer in meters to three significant figures.
