b = 3a + 20
\n" ); document.write( "c = a + 55
\n" ); document.write( "a + b + c = 180\r
\n" ); document.write( "\n" ); document.write( "-c + a = -55
\n" ); document.write( "a + b + c = 180\r
\n" ); document.write( "\n" ); document.write( "-2a - b = -125
\n" ); document.write( "b - 3a = 20\r
\n" ); document.write( "\n" ); document.write( "-5a = -105
\n" ); document.write( "a = 21 degrees
\n" ); document.write( "b = 83 degrees
\n" ); document.write( "c = 76 degrees
\n" ); document.write( "
\n" );
