In a parallelogram, opposite angles are equal, and adjacent angles are supplementary (they add up to 180 degrees).
Given that angle X measures 35 degrees, angle Z, which is opposite to angle X, also measures 35 degrees.
Now, to find the measures of angles W and Y, we use the fact that angles X and W are supplementary:
\[ \text{Angle W} = 180^\circ - \text{Angle X} = 180^\circ - 35^\circ = 145^\circ \]
Since angle Y is opposite angle W, angle Y also measures 145 degrees.
Therefore, the interior angle measures of angles W and Y are:
- Angle W: 145 degrees
- Angle Y: 145 degrees
