A wheelchair ramp is said to have an angle of 4.5° with the ground. the deck at the top of the ramp is 20 inches above ground level.
a) how long should the ramp be? round your answer to the nearest tenth of an inch.
c) how far from the deck should the ramp begin? Round your answer to the nearest tenth of an inch.

length: 20/x = sin 4.5°
distance: 20/x = tan 4.5°
