In this diagram, we observe two triangles. Based on the setup, it looks like the triangles are either similar or involve parallel lines, since the two lines with red arrows suggest that corresponding segments are proportional. 

Let's summarize the given information:
- Two parallel lines are marked with red arrows.
- The sides of the triangle are given as:
  - Left vertical side: 2 units (top) and 1 unit (bottom).
  - Right slant side: \( 2x - 4 \) units for the top segment and 2 units for the bottom segment.

### Setup for solving \( x \):
Since the lines are parallel and the triangles share an angle, the two triangles are similar by the Basic Proportionality Theorem (also called Thales' Theorem). This theorem states that if a line is drawn parallel to one side of a triangle and intersects the other two sides, then the two triangles formed are similar, and corresponding sides are proportional.

Thus, we can set up the following proportion for the corresponding sides:

\[
\frac{\text{left side top}}{\text{left side bottom}} = \frac{\text{right side top}}{\text{right side bottom}}
\]

Substituting the values:

\[
\frac{2}{1} = \frac{2x - 4}{2}
\]

Now, we can solve for \( x \):

1. Cross-multiply:
\[
2 \times 2 = 1 \times (2x - 4)
\]
\[
4 = 2x - 4
\]

2. Add 4 to both sides:
\[
4 + 4 = 2x
\]
\[
8 = 2x
\]

3. Divide by 2:
\[
x = 4
\]

Thus, \( x = 4 \).
