To find the value of \( x \), we need to set the two angles equal to each other, assuming they are the same angle. Thus, we can set up the equation:

\[
3x - 7 = x + 15
\]

Next, we'll solve for \( x \).

1. Subtract \( x \) from both sides:
\[
3x - x - 7 = 15
\]

2. Simplify:
\[
2x - 7 = 15
\]

3. Add 7 to both sides:
\[
2x = 22
\]

4. Divide by 2:
\[
x = 11
\]

Thus, the value of \( x \) is \( 11 \).

The answer is **B. 11**.
