Transcribed Image Text:The image presents a diagram of a triangle with an exterior angle. The task is to find the value of \( x \).
### Diagram Details:
- The triangle is shown with two angles marked inside and one exterior angle.
- One interior angle of the triangle is labeled as \( 2x - 6 \).
- Another interior angle is unlabeled.
- The exterior angle, adjacent to the side of the triangle with the angle of \( 2x - 6 \), is labeled as \( 6 \).
### Explanation:
The problem involves understanding the relationship between the interior angles of a triangle and its exterior angle. According to the exterior angle theorem, the exterior angle is equal to the sum of the two non-adjacent interior angles.
**Objective:** Find the value of \( x \) that satisfies the equation derived from this relationship.
This exercise helps in understanding angle relationships within a triangle and applying algebraic methods to solve for \( x \).
