Step 1:
: Identify the given information and what we need to find.

We are given that line l is parallel to line n, and we have the following angle measures: $|m\angle 1| = 135^{\circ}$, $|m\angle 2| = 55^{\circ}$, and $|m\angle 3| = 45^{\circ}$.
We need to find the value of x that makes line k parallel to line l and then state the converse that justifies our answer.

Step 2:
: Use the given angles to find the measure of $\angle 4$.

m\angle 4 = m\angle 1 = 135^{\circ}

Step 3:
: Find the measure of $\angle 5$ using the given angle $\angle 2$.

m\angle 5 = m\angle 2 = 55^{\circ}

Step 4:
: Determine the measure of $\angle 6$ based on $\angle 5$ and the line k.

m\angle 6 = m\angle 5 = 55^{\circ}

Step 5:
: Find the measure of $\angle 7$ based on $\angle 3$ and the linear pair relationship with $\angle 4$.

m\angle 7 + m\angle 3 = 180^{\circ} m\angle 7 = 180^{\circ} - m\angle 3 m\angle 7 = 180^{\circ} - 45^{\circ} m\angle 7 = 135^{\circ}

Step 6:
: Compare the measures of $\angle 4$ and $\angle 7$ to determine the value of x.

x = 135^{\circ}

Step 7:
: State the converse that justifies our answer.

The converse of the parallel lines theorem that justifies our answer is: If two lines are cut by a transversal and the corresponding angles are congruent, then the two lines are parallel.

Final Answer

The value of x that makes line k parallel to line l is 135$^\circ$, and this is justified by the converse of the parallel lines theorem: If two lines are cut by a transversal and the corresponding angles are congruent, then the two lines are parallel.
