To find the value of \( x \) given that the vertical angles are congruent, we can set up the equation based on the fact that the two angles are equal to each other:

\[
5x - 3 = 77
\]

Now, we will solve for \( x \).

1. First, add \( 3 \) to both sides of the equation:

\[
5x - 3 + 3 = 77 + 3
\]
\[
5x = 80
\]

2. Next, divide both sides by \( 5 \):

\[
x = \frac{80}{5}
\]
\[
x = 16
\]

Thus, the value of \( x \) is \( 16 \).
