\n" ); document.write( "the two supplementary angles add up to 180°\r
\n" ); document.write( "\n" ); document.write( "if one of them is $\"alpha\"$ and the other one is $\"beta\"$ , then we have\r
\n" ); document.write( "\n" ); document.write( " $\"alpha+%2B+beta+=+180\"$ ........if $\"alpha=+2beta\"$ , then\r
\n" ); document.write( "\n" ); document.write( " $\"2beta+%2B+beta+=+180\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"3beta++=+180\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"beta++=+180%2F3\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"beta++=+60\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"alpha=+2%2A60\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"alpha=+120\"$ \r
\n" ); document.write( "\n" ); document.write( "so, your angles are: $\"alpha=+120\"$ and $\"beta++=+60\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
