x = angle
\n" ); document.write( "180 - x = supplement
\n" ); document.write( "x = (180-x) - 30
\n" ); document.write( "simplify.
\n" ); document.write( "x = 180 - x - 30
\n" ); document.write( "add x to both sides
\n" ); document.write( "2x = 180 - 30
\n" ); document.write( "simplify.
\n" ); document.write( "2x = 150
\n" ); document.write( "divide both side by 2.
\n" ); document.write( "x = 75
\n" ); document.write( "angle = 75
\n" ); document.write( "supplement = 180 - 75 = 105
\n" ); document.write( "75 is 30 less than 105.
\n" ); document.write( "solution is that the measure of the supplement is 105.
\n" ); document.write( " \n" ); document.write( "
