The problem involves a pentagon where two of the interior angles are labeled as \(x\) and \(y\), and the rest of the angles are given. To solve for \(x\) and \(y\), we need to apply some geometric principles. Let's analyze the problem step-by-step.

### Step 1: Calculate the sum of the interior angles of the pentagon
The formula for the sum of the interior angles of a polygon with \(n\) sides is:
\[
\text{Sum of interior angles} = (n-2) \times 180^\circ
\]
For a pentagon, \(n = 5\), so the sum of the interior angles is:
\[
\text{Sum of interior angles} = (5-2) \times 180^\circ = 3 \times 180^\circ = 540^\circ
\]

### Step 2: Add the given angles and solve for \(x\) and \(y\)
The angles in the pentagon are:
- \(135^\circ\)
- \(x^\circ\)
- \(y^\circ\)
- An exterior angle of \(100^\circ\) corresponding to an interior angle of \(80^\circ\) (since interior and exterior angles add up to \(180^\circ\)).
- An exterior angle of \(40^\circ\), corresponding to an interior angle of \(140^\circ\).

Thus, we have the equation:
\[
135^\circ + x^\circ + y^\circ + 80^\circ + 140^\circ = 540^\circ
\]
Simplifying the known values:
\[
355^\circ + x^\circ + y^\circ = 540^\circ
\]
Now subtract \(355^\circ\) from both sides:
\[
x^\circ + y^\circ = 185^\circ
\]

### Step 3: Use the given relationship between \(x\) and \(y\)
The diagram suggests that \(x\) and \(y\) are adjacent angles, likely indicating a supplementary relationship. Since no other information is given about their relationship (such as them being equal), let's conclude that the two angles must add up to \(185^\circ\). Therefore, \(x + y = 185^\circ\).

This gives us an equation to work with. You can now choose values or additional assumptions based on whether they are supplementary or equal.

Would you like more details on how to explore or verify this relationship? Here are some relevant questions for practice:

1. How do we verify if \(x\) and \(y\) must be supplementary or equal in this context?
2. Can we calculate exterior angles directly from the given interior angles?
3. How do we find interior angles in polygons with more than 5 sides?
4. What is the relationship between interior and exterior angles of polygons?
5. How can we determine angle measures using alternate geometric principles?

**Tip**: Always double-check if the diagram suggests any equal angles or supplementary conditions before solving!
