In the image, we have two angles formed by intersecting lines, with the measures of the angles given in terms of \(x\).

The angles are marked as:
- \( (4x + 1)^\circ \) (top-left)
- \( (2x - 19)^\circ \) (bottom-left)

These angles are vertical angles, which means they are congruent (equal to each other). Therefore, we can set their expressions equal and solve for \(x\):

\[
4x + 1 = 2x - 19
\]

### Step-by-step solution:

1. Subtract \(2x\) from both sides:

\[
4x - 2x + 1 = -19
\]
\[
2x + 1 = -19
\]

2. Subtract 1 from both sides:

\[
2x = -19 - 1
\]
\[
2x = -20
\]

3. Divide both sides by 2:

\[
x = \frac{-20}{2}
\]
\[
x = -10
\]

So, the value of \(x\) is \(-10\).
