For any triangle,
\n" ); document.write( "\"a%5B1%5D%2Ba%5B2%5D%2Ba%5B3%5D=180\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "\"a%5B1%5D=2%2Aa%5B2%5D\"
\n" ); document.write( "\"a%5B2%5D=%281%2F2%29a%5B1%5D\"
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "\"a%5B3%5D=a%5B1%5D-10\"
\n" ); document.write( "Substitute,
\n" ); document.write( "\"a%5B1%5D%2B%281%2F2%29a%5B1%5D%2Ba%5B1%5D-10=180\"
\n" ); document.write( "\"%285%2F2%29a%5B1%5D-10=180\"

\n" ); document.write( "\"highlight%28+a%5B1%5D=76%29\"degrees
\n" ); document.write( "Then
\n" ); document.write( "\"a%5B2%5D=%281%2F2%2976\"
\n" ); document.write( "\"highlight%28a%5B2%5D=38%29\"degrees
\n" ); document.write( "and,
\n" ); document.write( "\"a%5B3%5D=76-10\"
\n" ); document.write( "\"highlight%28a%5B3%5D=66%29\"degrees
