A 12 ft. ladder makes a 33o angle with the side of a house. To the nearest tenth of a foot how high up on the house does the ladder come?
I set it up 12xcos33 giving me 10.0
Set up is almost correct, but cos=adj/hyp. your setup will give you distance of the bottom of the ladder from the wall. Sin is Opp/Hyp, ergo height of the top of the ladder on the wall.
