In a circle, the measure of the angle formed by two lines radiating from a common point (the vertex of the angle) is half the measure of the arc that the angle subtends.

In this case, we have the following:

- \( m\angle ONP = 48^\circ \)
- \( m\arc{OP} = (4x - 48)^\circ \)

According to the relationship between the angle and the arc, we have:

\[
m\angle ONP = \frac{1}{2} m\arc{OP}
\]

Substituting the values we have:

\[
48 = \frac{1}{2} (4x - 48)
\]

Now, we'll solve for \( x \):

1. Multiply both sides by 2 to eliminate the fraction:

\[
96 = 4x - 48
\]

2. Add 48 to both sides:

\[
96 + 48 = 4x
\]
\[
144 = 4x
\]

3. Divide both sides by 4:

\[
x = \frac{144}{4}
\]
\[
x = 36
\]

Thus, the value of \( x \) is \( \boxed{36} \).
