\n" ); document.write( "complement is when two angles summed together is 90 deg.

\n" ); document.write( "Let x = \"the angle\"
\n" ); document.write( "then
\n" ); document.write( "90-x = the complement
\n" ); document.write( "180-x = the supplement
\n" ); document.write( ".
\n" ); document.write( "180-x = 3(90-x)-12
\n" ); document.write( "180-x = 270-3x-12
