### Understanding Inscribed Quadrilaterals

Examine the diagram, where quadrilateral \( H I J K \) is inscribed in circle \( \odot C \).

**Diagram Explanation:**
- The figure shows a circle \( \odot C \) with a quadrilateral \( H I J K \) inscribed in it. 
- Points \( H \), \( I \), \( J \), and \( K \) are on the circumference of the circle.
- There is an indicator of an angle \( \angle I J K \) measuring \( 112^\circ \) at vertex \( J \).
- The other given angle is \( \angle H K I \), which is unknown and needs to be calculated.

#### Problem Statement
**If \( m \angle I J K = 112^\circ \), what is \( m \angle I H K \)?**

Enter your answer as the number that correctly fills in the blank in the previous sentence, like this: 42

---

**Solution Approach:**
- Use the property of inscribed angles and the fact that opposite angles of an inscribed quadrilateral sum up to \( 180^\circ \).
- Given \( m \angle I J K = 112^\circ \), the opposite angle \( \angle I H K \) can be found using:
\[ 
m \angle I H K + m \angle I J K = 180^\circ
\]
\[ 
m \angle I H K + 112^\circ = 180^\circ
\]
\[ 
m \angle I H K = 180^\circ - 112^\circ 
\]
\[ 
m \angle I H K = 68^\circ 
\]
- Thus, \( m \angle I H K \) is \( 68^\circ \).

### Answer
\( m \angle I H K \) is 68.

Enter your answer as the number that correctly fills in the blank in the previous sentence, like this: 68
