\n" ); document.write( "let first angle = x\r
\n" ); document.write( "\n" ); document.write( "second angle = 2x\r
\n" ); document.write( "\n" ); document.write( "third angle = 2x +x\r
\n" ); document.write( "\n" ); document.write( "sum of angles = 180\r
\n" ); document.write( "\n" ); document.write( "=> x + 2x +(x+2x) = 180\r
\n" ); document.write( "\n" ); document.write( "=> 6x = 180\r
\n" ); document.write( "\n" ); document.write( "=> x= 30\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, angles are 30, 60 and 90 degree.\r
\n" ); document.write( "\n" ); document.write( "
