    \[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\] use any function cos B sin B or tan B

    Yea I got that far, but when I get my answer, for example lets use sin. \[\sin \theta=\frac{ 60.1 }{ 66.4 }\]
