Math Is Fun Forum

D: uhhh still confused why didnt you add the two

here is the website http://www.physicsclassroom.com/Class/1DKin/u1l6c.cfm

Bundy why did you switch around the two big equations in the start?

It wasn't my decision to go on vacation but I will still be online
And I found a book about pre algebra but I'll still study here

ok woops didnt realize that xD ive only really been exploring the forums

ok so first im gonna pick Sin because im trying to find the opposite and i know the hypotenuse. so the sin equation is Opp/Hyp = Sin(x) now replace the vars and i get Opp/12 = Sin(32) so now i find out what the sin of 32 equals and i get 0.52 now i do 12x0.52 and i get 6.35 now to double check i do 6.35/12 which equals 0.52 now i click sin-¹ so the length from A to B is 6.35 cm

when do you know when you have to subtract or add like on this problem? http://www.mathopolis.com/questions/a.php?id=345&ansno=1896&site=1
