Let's analyze the given information from the image:

- We have triangle \( \triangle ABC \) with points \( D, E, \) and \( C \) inside or near the triangle.
- The measures provided are:
  - \( AC = CD \) (which means \( \triangle ACD \) is isosceles).
  - Angle \( \angle EBC = 45^\circ \).
  - Angle \( \angle ACD = 104^\circ \).
- We need to determine the value of \( x^\circ \).

### Step 1: Finding angles in the isosceles triangle \( \triangle ACD \)

Since \( AC = CD \), the base angles \( \angle DAC \) and \( \angle CDA \) must be equal. We know that:
\[ \angle ACD = 104^\circ \]
The sum of angles in a triangle is \( 180^\circ \). Let the base angles each be \( \theta \). Then:
\[
\theta + \theta + 104^\circ = 180^\circ
\]
\[
2\theta = 180^\circ - 104^\circ
\]
\[
2\theta = 76^\circ
\]
\[
\theta = 38^\circ
\]

So, \( \angle DAC = 38^\circ \) and \( \angle CDA = 38^\circ \).

### Step 2: Using the angles in triangle \( \triangle ABE \)

To find \( x \), we need to use the information about triangle \( \triangle ABE \). Using the straight line property, we know that:
\[
\angle DAC + \angle BAE = 180^\circ
\]
Therefore, substituting \( \angle DAC = 38^\circ \):
\[
38^\circ + \angle BAE = 180^\circ
\]
\[
\angle BAE = 142^\circ
\]

However, we know that \( \angle EBC = 45^\circ \) is part of the triangle \( \triangle ABE \), which means we need to calculate based on this additional information.

### Conclusion for \( x \)

If we calculate these properly, we'd proceed with calculating other angles in smaller triangles. For now, based on the isosceles property and given conditions we found, we'd do these checks.
