Let the angles be $\"a\"$ and $\"90+-+a\"$
\n" ); document.write( "given:
\n" ); document.write( " $\"4%2F5+=+a%2F%2890+-+a%29\"$
\n" ); document.write( " $\"5a+=+4%2A%2890+-+a%29\"$
\n" ); document.write( " $\"5a+=+360+-+4a\"$
\n" ); document.write( " $\"9a+=+360\"$
\n" ); document.write( " $\"a+=+40\"$
\n" ); document.write( " $\"90+-+a+=+50\"$
\n" ); document.write( "The angles are 40 degrees and 50 degrees \n" ); document.write( "

\n" );
