Answer:
Line p must be drawn so that it can lie in the same plane as line l.
Step-by-step explanation:
Let us first rewrite main information from this question:
- there is plane A containing line m
- there is plane B containing line n
- lines m and n are perpendicular
And, then, we have a new line l on a plane A. Since lines are infinite and line l is slightly diagonal, that means that it's going to intersect plane B at some point.
Now, since this newly drawn line p is parallel to line l, it will have the same features as l, meaning that it will also intersect plane B.
Since it's impossible for a line to intersect a plane containing it, that means that line p lies in the same line as line l.
