The supplement of an angle is 60 degrees less than twice the supplement of the complement of the angle.
\n" ); document.write( "Let x = the angle
\n" ); document.write( "then
\n" ); document.write( "90-x = complement of angle
\n" ); document.write( "180-x = supplement of angle
\n" ); document.write( "180-(90-x) = 90+x = supplement of complement of angle
\n" ); document.write( ".
\n" ); document.write( "180-x = 2(90+x) - 60
\n" ); document.write( "180-x = 180+2x -60
\n" ); document.write( "-x = 2x -60
\n" ); document.write( "-x+60 = 2x
\n" ); document.write( "60 = 3x
\n" ); document.write( "20 degrees = x\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
