### Geometry Problem: Finding the Value of x

**1) Find the value of x.**

#### Diagram:
- The diagram shows a circle with two line segments intersecting inside the circle.
- One of the angles formed by the intersecting lines inside the circle is labeled as \( x^\circ \).
- One of the angles on the left side of the circle is labeled as \( 40^\circ \).
- Another angle on the right side of the circle is labeled as \( 96^\circ \).
  
To solve the problem, remember that the angle \( x^\circ \) inside the circle, formed by the intersecting lines, is related to the external angles \( 40^\circ \) and \( 96^\circ \). The formula we use for such situations is:

\[ x = \frac{1}{2} \times (\text{angle1} + \text{angle2}) \]

Substitute the given angles:

\[ x = \frac{1}{2} \times (40^\circ + 96^\circ) \]

Now, calculate:

\[ x = \frac{1}{2} \times 136^\circ \]
\[ x = 68^\circ \]

Therefore, the value of \( x \) is \( 68^\circ \).
