You can put this solution on YOUR website!
let 1st angle = x
\n" ); document.write( "so the 2nd angle = 180 - x (because they are supplementary)
\n" ); document.write( "1st angle = 2 times of 2nd angle
\n" ); document.write( "x = 2(180 - x)
\n" ); document.write( "x = 360 - 2x
\n" ); document.write( "x + 2x = 360
\n" ); document.write( "3x = 360
\n" ); document.write( "x = 360/3
\n" ); document.write( "x = 120\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so, the 1st angle = x = 120 degrees
\n" ); document.write( "and the 2nd angle = 180 - x = 180 - 120 = 60 degrees
\n" ); document.write( "
\n" );
