In a plane, line k is parallel to line l and line j is perpendicular to line l. what can you conclude about the relationship between lines j and k

Given that line K is parallel to line L and line J is perpendicular to line L, the relationship between like J and K is also perpendicularity. That is, if lines K and J also meets or intersects at a right angle (90 degrees), similar to how line J and L intersects, then they're said to be perpendicular.
