The correct statements about the missing angles are:
w > y
x + y = w
w > x
How to find the angles in the triangle?
The sum of angles in a triangle is 180 degrees.
Now, we know that the sum of two opposite interior angles is equal to an exterior angle. Thus:
x + y = w
We also see that w is greater than 90 degrees while z is less than 90 degrees. Thus:
w > z
Each of the interior angles are less than 90 degrees and as such:
w > x and as well same applies to w > y.
