To find the value of $x$, we need to use the property that the given lines $p$ and $q$ are parallel, and the transversal $t$ intersects them.

Step-by-Step Solution:

1. Identify Corresponding Angles: Since $p \parallel q$, and $t$ is a transversal, the angle labeled $x + 50$ is corresponding to the angle labeled $x$.

2. Set Up the Equation: Corresponding angles are equal when two parallel lines are cut by a transversal. Therefore, we can set the angles equal to each other:

   $x + 50 = x$

3. Solve for $x$: Subtract $x$ from both sides:

   $x + 50 - x = x - x$

   This simplifies to:

   $50 = 0$

   This result suggests that there is some mistake in the given figure or labeling, as the equation $x + 50 = x$ would imply that $50 = 0$, which is not possible.

Conclusion:

The value of $x$ cannot be determined based on the given information, as there seems to be an error in the figure or problem statement.
