Answer:
The correct options are;
Lines l and n are perpendicular
Lines m and n are perpendicular
Step-by-step explanation:
Where two lines l an m are said to be perpendicular to a given line n, then we have;
1) When l and m are in different planes,
a) l and m can be parallel lines to each other or
b) l and m can be perpendicular to each other or
c) l and m can be at an angle x, to each other
2) When l and m intersect with the line n at a point p, then, we have;
l and m must be in the same plane with each other.
