1st angle = x
\n" ); document.write( "2nd angle = 3x + 20\r
\n" ); document.write( "\n" ); document.write( "x + (3x + 20) = 180
\n" ); document.write( "4x + 20 = 180
\n" ); document.write( "4x + 20 - 20 = 180 - 20
\n" ); document.write( "4x = 160
\n" ); document.write( "4x/4 = 160/4
\n" ); document.write( "x = 40\r
\n" ); document.write( "\n" ); document.write( "check:
\n" ); document.write( "40 + (3(40) + 20) = 180
\n" ); document.write( "40 + (120 + 20) = 180
\n" ); document.write( "40 + 140 = 180
\n" ); document.write( "180 = 180
