According to the information given in the picture, how many degrees is x?

To solve for the angle \( x \) in the image, we can use the following steps:

1. **Identify the angles:**
   - The angle marked \( 78^\circ \) is given.
   - The angle \( \alpha + 26^\circ \) is also given.
   - The angle \( \alpha \) is marked adjacent to \( x \).

2. **Observe the relationship between angles:**
   - The angle \( 78^\circ \) and \( \alpha + 26^\circ \) are alternate interior angles, which means they are equal. Hence:
     \[
     \alpha + 26^\circ = 78^\circ
     \]
     Solving for \( \alpha \):
     \[
     \alpha = 78^\circ - 26^\circ = 52^\circ
     \]

3. **Find the value of \( x \):**
   - The angle \( x \) and angle \( \alpha \) (which is \( 52^\circ \)) form a linear pair (they are supplementary), so:
     \[
     x + \alpha = 180^\circ
     \]
     Substitute \( \alpha = 52^\circ \):
     \[
     x + 52^\circ = 180^\circ
     \]
     \[
     x = 180^\circ - 52^\circ = 128^\circ
     \]

Thus, the value of \( x \) is \( \boxed{128^\circ} \).

2. How do you determine if two angles are supplementary?
3. What are the properties of linear pairs in geometry?
4. Can you calculate the angle \( \alpha + 26^\circ \) directly from the diagram?
5. What role do parallel lines play in the equality of angles?
6. How would the problem change if \( \alpha + 26^\circ \) was not equal to \( 78^\circ \)?
7. What is the relationship between the angles formed by a transversal cutting two parallel lines?
8. How can the sum of angles in a triangle be used to find missing angles?

**Tip:** Always look for relationships between angles such as supplementary, complementary, and vertical angles when solving problems involving intersecting lines and angles.
