given:\r
\n" ); document.write( "\n" ); document.write( "angle \"x=72\"
\n" ); document.write( "find: the supplementary angle \"y\"\r
\n" ); document.write( "\n" ); document.write( "Supplementary angles are pairs of angles that add up to \"180\" degrees. Thus the supplement of an angle of \"x\" degrees is an angle of \"y=%28180-x%29\" degrees. \r
\n" ); document.write( "\n" ); document.write( "\"y=%28180+-x%29\"...plug in \"x\"\r
\n" ); document.write( "\n" ); document.write( "\"y=%28180+-72%29\"\r
\n" ); document.write( "\n" ); document.write( "\"y=108\"degrees
\n" ); document.write( "
