You can put this solution on YOUR website!
This has to be drawn. I am assuming that XY= 9.9, otherwise this can't be solved.
\n" ); document.write( "y/sin Y=z/sin Z
\n" ); document.write( "13/sin 78=99/sin Z
\n" ); document.write( "13.29=9.9/sin Z
\n" ); document.write( "sin Z=9.9/13.29
\n" ); document.write( "=0.7449.
\n" ); document.write( "take the arc sin of that, and Z=48.15 degrees. \n" ); document.write( "

\n" );
