supplementary angles add up to 180.
\n" ); document.write( "The ratio is 3:9.
\n" ); document.write( "The ratio points are 12.
\n" ); document.write( "take 180 and divide it by 12 to figure out hoe many degrees are in 1 ratio point.
\n" ); document.write( "180/12=15
\n" ); document.write( "now multiply the ratio by 15
\n" ); document.write( "45:135
\n" ); document.write( "The larger angle is 135
\n" ); document.write( "
\n" );
