Angles are $\"supplementary\"$ if they add to $\"180\"$ °.\r

\n" ); document.write( "\n" ); document.write( " $\"alpha=102\"$ °\r
\n" ); document.write( "\n" ); document.write( "find $\"beta\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"beta=180-alpha\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"beta=180-102\"$ \r
