Complementary angles add to 90:
\n" ); document.write( "3x + y = 90
\n" ); document.write( "--> y = 90-3x
\n" ); document.write( "--> complementary angle is 90-3x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Supplementary angles add to 180:
\n" ); document.write( "3x + y = 180
\n" ); document.write( "--> y = 180-3x
\n" ); document.write( "--> supplementary angle is 180-3x\r
\n" ); document.write( "
