    30-60-90 triangle how you find all 3 sides of that triangle here is a link! http://openstudy.com/users/masonman#/updates/554671efe4b0629c5c69ef37 after that sin cosine and tan definition \[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\] (mhm sorry i have 5 mints otherwise i would love to explain it) btw if u don't get it then wait for other user to explain it better than me ofc!! -)
