\r\n" );
document.write( "In any triangle,\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, if all you want is just the Third angle, then\r\n" );
document.write( "Just add the two given angles 65°+35°, getting 100°.\r\n" );
document.write( "Then subtract that from 180°.\r\n" );
document.write( "\r\n" );
document.write( "180° - 100° = 80°\r\n" );
document.write( "\r\n" );
document.write( "So the third angle is 80°.  That's the answer!\r\n" );
document.write( "\r\n" );
document.write( "Then the 2(x-10) is not necessary at all.\r\n" );
document.write( "\r\n" );
document.write( "--------------------------------------------------\r\n" );
document.write( "\r\n" );
document.write( "However, if your teacher wants you to find x, then \r\n" );
document.write( "\r\n" );
document.write( "2(x-10) = 80°\r\n" );
document.write( " 2x-20° = 80°\r\n" );
document.write( "   +20°  +20°\r\n" );
document.write( " 2x     = 100°\r\n" );
document.write( "  x     = 50°\r\n" );
