\n" ); document.write( "\n" ); document.write( "The three angles total 180 degrees.
\n" ); document.write( " (x+10) + (2x) + (2x-30) = 180
\n" ); document.write( " 5x - 20 =180
\n" ); document.write( "add 20 to each side
\n" ); document.write( " 5x = 200
\n" ); document.write( "divide each side by 5
\n" ); document.write( " x = 40
\n" ); document.write( "Since B = 2x, B = 80
\n" ); document.write( "
