1) Find the interior angle using relations of angles in straight line I.e ( sumofanglesinastraightlineis180) and we know the sum of all the interior angle of quadrilateral is 360 degree .
The answer is 3.4 because 30 can’t be divided equally into 9, reason being that 9 x 30 = 270 which doesn’t make sense, so you have to divide 30 equally into 9 parts then turn it into a ratio.
