The measure of the angle is 81 degrees more than twice that of its supplement.\r
\n" ); document.write( "\n" ); document.write( "I have:
\n" ); document.write( "x+(2x+81)=180
\n" ); document.write( "----------
\n" ); document.write( "x = the angle
\n" ); document.write( "180 - x = its supplement
\n" ); document.write( "x = 2*(180 - x) + 81
\n" ); document.write( "x = 360 - 2x + 81 = -2x + 441
\n" ); document.write( "3x = 441
\n" ); document.write( "x = 147
\n" ); document.write( "
\n" ); document.write( "
\n" );
