To find the value of \( x \) in the given angles, we can use the property that vertical angles are equal. Since \( m∠2 = 135° \) and \( m∠4 = (4x + 15)° \), we set them equal to each other:

\[
135 = 4x + 15
\]

Now, we solve for \( x \):

1. Subtract 15 from both sides:

\[
135 - 15 = 4x
\]
\[
120 = 4x
\]

2. Divide both sides by 4:

\[
x = \frac{120}{4} = 30
\]

So, the value of \( x \) is \( 30 \).

The answer is **30**.
