Hint: If \"∠a and ∠b are supplementary\", then \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "m∠a + m∠b = 180\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So (2x + 4) + (4x - 10) = 180\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
