document.write( "the second is 2 times the third
\n" );
document.write( "Let x and 2x represent the third and second angles respectively
\n" );

\n" );
document.write( "72° + 2x + x = 180°
\n" );
document.write( "solving for x
\n" );
document.write( "     3x = 108°
\n" );
document.write( "      x = 36°, the second angle.  The third is 72°  (2*36°)\r
