Every quadrilateral in a plane contains a total of 360 degrees.
\n" ); document.write( "If the ratio of the interior angles is 4:9:5:6, we can set them equal to
\n" ); document.write( "4x, 9x, 5x and 6x, and then set their sum equal to 360 degrees.\r
\n" ); document.write( "\n" ); document.write( "Thus 4x + 9x + 5x + 6x = 360
\n" ); document.write( "24x = 360
\n" ); document.write( "x = 15
\n" ); document.write( "and the angles are then
\n" ); document.write( "60, 135, 75, and 90 degrees, respectively.
