document.write( "you get 90°.\r\n" );

document.write( "Then to say that when you add them, you get 90°, you put an equal \r\n" );
document.write( "sign after that, and then put 90° after that, like this:\r\n" );
document.write( "\r\n" );
document.write( "     (3x-40)° + (4x+18)° = 90°\r\n" );
document.write( "\r\n" );
document.write( " Then you drop the ° marks and solve for x:\r\n" );
document.write( "\r\n" );
document.write( "       (3x-40) + (4x+18) = 90\r\n" );
