Given:-the ratio of the measures of the interior angles of a quadrilateral is 3:5:7:9
\n" ); document.write( "
\n" ); document.write( "We know the sum of all the interior angle of a quadilateral = 360\r
\n" ); document.write( "\n" ); document.write( "let the four angles be 3x, 5x, 7x, 9x (since the ratio of angles are given)\r
\n" ); document.write( "\n" ); document.write( "By angle sum property of a quardilateral we get\r
\n" ); document.write( "\n" ); document.write( "3x + 5x + 7x + 9x = 360\r
\n" ); document.write( "\n" ); document.write( "now i hope you can calculate the value of x from there and therby you can get the value of all the four angles ,\r
\n" ); document.write( "\n" ); document.write( "hope this will help you,
