The problem asks us to find the value of \( x \) and then determine the missing angle measures of the polygon shown. Here's how we can solve it:

### Step 1: Set Up the Equation
The polygon is a pentagon, and the sum of its interior angles is given as \( 540^\circ \). The interior angles are labeled as \( x \), \( x \), \( x-30^\circ \), \( x-30^\circ \), and \( x-30^\circ \).

### Step 2: Write the Equation for the Sum of the Angles
We add all the angles together and set them equal to \( 540^\circ \):

\[
x + x + (x - 30) + (x - 30) + (x - 30) = 540
\]

Simplify the equation:

\[
5x - 90 = 540
\]

### Step 3: Solve for \( x \)
Add 90 to both sides:

\[
5x = 630
\]

Divide by 5:

\[
x = 126
\]

### Step 4: Find the Missing Angle Measures
Substitute \( x = 126 \) into the expressions for each angle:

- For the angles labeled \( x \): 
  \[
  x = 126^\circ
  \]

- For the angles labeled \( x - 30 \): 
  \[
  x - 30 = 126 - 30 = 96^\circ
  \]

### Final Answers:
- \( x = 126 \)
- Angles labeled \( x - 30 \) are \( 96^\circ \).
