Let $\"+A+\"$ = one of the unknown angles in degrees
\n" ); document.write( "The other unknown angle is:
\n" ); document.write( " $\"+3A+-+3+\"$ degrees
\n" ); document.write( "------------------------
\n" ); document.write( "The sum of the angles is $\"+180+\"$ degrees, so
\n" ); document.write( " $\"+47+%2B+A+%2B+3A+-+3+=+180+\"$
\n" ); document.write( " $\"+4A+=+180+-+47+%2B+3+\"$
\n" ); document.write( " $\"+4A+=+136+\"$
\n" ); document.write( " $\"+A+=+34+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+3A+-+3+=+3%2A34+-+3+\"$
\n" ); document.write( " $\"+3A+-+3+=+99+\"$
\n" ); document.write( "----------------
\n" ); document.write( "The 2 remaining angles are 34 degrees and 99 degrees
\n" ); document.write( "---------------------
\n" ); document.write( "check answer:
\n" ); document.write( " $\"+47+%2B+A+%2B+3A+-+3+=+180+\"$
\n" ); document.write( " $\"+47+%2B+34+%2B+3%2A34+-+3+=+180+\"$
\n" ); document.write( " $\"+81+%2B+102+-+3+=+180+\"$
\n" ); document.write( " $\"+81+%2B+99+=+180+\"$
\n" ); document.write( " $\"+180+=+180+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
