The problem asks to find \( m \angle ABD \) under the given conditions:

1. \( \overline{BD} \) bisects \( \angle CBE \),
2. \( \overline{BC} \perp \overline{BA} \) (i.e., \( \angle ABC = 90^\circ \)),
3. \( m \angle CBD = (3x + 25)^\circ \),
4. \( m \angle DBE = (7x - 19)^\circ \).

Let's break this down step by step:

### Step 1: Understanding the angle relationships
Since \( \overline{BD} \) bisects \( \angle CBE \), we know:
\[
m \angle CBD = m \angle DBE
\]
This gives us the equation:
\[
3x + 25 = 7x - 19
\]

### Step 2: Solve for \( x \)
Solving the equation:
\[
3x + 25 = 7x - 19
\]
Subtract \( 3x \) from both sides:
\[
25 = 4x - 19
\]
Add 19 to both sides:
\[
44 = 4x
\]
Divide by 4:
\[
x = 11
\]

### Step 3: Find the measures of \( \angle CBD \) and \( \angle DBE \)
Substitute \( x = 11 \) into the expressions for \( m \angle CBD \) and \( m \angle DBE \):
\[
m \angle CBD = 3(11) + 25 = 33 + 25 = 58^\circ
\]
\[
m \angle DBE = 7(11) - 19 = 77 - 19 = 58^\circ
\]
Thus, \( m \angle CBE = m \angle CBD + m \angle DBE = 58^\circ + 58^\circ = 116^\circ \).

### Step 4: Find \( m \angle ABD \)
Since \( \overline{BC} \perp \overline{BA} \), we know that \( \angle ABC = 90^\circ \). We are looking for \( m \angle ABD \), and because:
\[
m \angle ABC + m \angle ABD + m \angle DBC = 180^\circ
\]
Substitute the known values:
\[
90^\circ + m \angle ABD + 58^\circ = 180^\circ
\]
Solve for \( m \angle ABD \):
\[
m \angle ABD = 180^\circ - 90^\circ - 58^\circ = 32^\circ
\]

Thus, \( m \angle ABD = 32^\circ \).
