Since the two angles are vertical angles, they are equal to each other. We can set the expressions for the angles equal to each other:

\[
6x - 15 = 4x + 5
\]

Now, let's solve for \(x\):

1. Subtract \(4x\) from both sides:

\[
6x - 4x - 15 = 5
\]
\[
2x - 15 = 5
\]

2. Add \(15\) to both sides:

\[
2x = 20
\]

3. Divide by \(2\):

\[
x = 10
\]

Now we can find the measure of each angle by substituting \(x = 10\) back into either expression:

\[
6x - 15 = 6(10) - 15 = 60 - 15 = 45°
\]

\[
4x + 5 = 4(10) + 5 = 40 + 5 = 45°
\]

Thus, both angles measure \(45°\).

The measure of each angle is \( \text{45°} \).
