I don't understand why we can't determine that x angle is bigger than z+y, because x+y+z=180 degree am I right or not!!!
So x it's bigger than 90.
Thanks a lot.

The problem doesn't specify that x>90, so we can't assume it. With the information given, we can't tell whether x>90.

The problem with this aspect of the test is that the previous question listed here required us to use basic intuition with the diagram to determine that the point P is not on the x-axis. This problem is similar. There is no actual rule as when or when not to use your visual intuition which is extremely frustrating and grossly unfair.

The problem does specify its larger than 90 because we have eyes and it's a picture of an obtuse angle...
