### Geometry: Angle Measurement

#### Problem Statement:
**Given:**  
If \( x = 34^\circ \), find the measure of the angle in which \( ?^\circ \) appears.

#### Diagram Description:
To the right of the problem statement, there is a diagram showing an angle \( x \) and a second angle labeled as \( ?^\circ \). The angles are depicted such that they together make a right angle (90°).

#### Solution:
1. Recognize that the right angle (90°) is composed of two smaller angles: \( x \) and \( ?^\circ \).
2. Since \( x = 34^\circ \), the equation to find \( ?^\circ \) is:
   \[
   90^\circ = x + ?^\circ
   \]
3. Substituting \( x \) with its given value:
   \[
   90^\circ = 34^\circ + ?^\circ
   \]
4. Solving for \( ?^\circ \):
   \[
   ?^\circ = 90^\circ - 34^\circ = 56^\circ
   \]

#### Answer:
The measure of the angle in which \( ?^\circ \) appears is:
```markdown
56°
```

Note: The diagram shown helps visualize that the given angle \( x \) and the unknown angle \( ?^\circ \) together form a right angle, emphasizing the complementary nature of the angles.
