Let $\"+x+\"$ = one of the angles
\n" ); document.write( " $\"+180+-+x+\"$ = the other angle
\n" ); document.write( "-----------------------------
\n" ); document.write( " $\"+2%2F7+=+x+%2F+%28+180+-+x+%29+\"$
\n" ); document.write( "Multiply both sides by $\"+7%2A%28+180+-+x+%29+\"$
\n" ); document.write( " $\"+2%2A%28+180+-+x+%29+=+7x+\"$
\n" ); document.write( " $\"+360+-+2x+=+7x+\"$
\n" ); document.write( " $\"+9x+=+360+\"$
\n" ); document.write( " $\"+x+=+40+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+180+-+x+=+180+-+40+\"$
\n" ); document.write( " $\"+180+-+x+=+140+\"$
\n" ); document.write( "---------------------
\n" ); document.write( "The angles are 40 degrees and 140 degrees
\n" ); document.write( "---------------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+2%2F7+=+x+%2F+%28+180+-+x+%29+\"$
\n" ); document.write( " $\"+2%2F7+=+40+%2F+140+\"$
\n" ); document.write( " $\"+2%2F7+=+4%2F14+\"$
\n" ); document.write( " $\"+2%2F7+=+2%2F7+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
