ANSWER

Line K is not parallel to line L.

Step-by-step explanation

The two angles given are alternate exterior angles. When a line crosses two parallel lines, the alternate exterior angles always sum up to 180 degrees.

So, to confirm if line L is parallel to line K, we check to see if the two given angles sum up to 180 degrees:


\begin{gathered} 122+68 \\ \Rightarrow190\degree \end{gathered}

Since they don't sum up to 180 degrees, Line K is not parallel to line L.
