    \[\huge\rm csc \theta =\frac{ 1 }{ \sin \theta }\] and sin theta \[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\]

    the hypotenuse is ALWAYS the longest side it is always opposite the 90 degree angle |dw:1433388057774:dw|

    with relation to angle theta (symbol \(\large \theta\)), the 12 is the opposite side because it is the furthest from angle theta that you can get the 9 is the adjacent side because it is touching the angle theta |dw:1433388118783:dw|

    well as Nnesha pointed out, sine = opposite/hypotenuse so you just found out that sin(theta) = 4/5

    sin(theta) = 4/5 1/sin(theta) = 5/4 ... take the reciprocal of both sides csc(theta) = 5/4
