Here, as per the supplementary angle rule (the sum of angles on a line is 180°) , we can find that the angles AOD and BOC are 90°.
Similarly, using the complementary angle rule (the sum of angles in a right angle is 90°), we can find that angle EOD is 40°.
Now, we can see that angle z is opposite to the angle EOD, hence z=40.
Implying that 50>z
