We first write the angle between them as the difference between individual angles. We then apply the trig identity of difference of angles to evaulate the tan of this angle. We understand the meaning behind the negative values. Finally, we practice a problem that uses this formula.

In both the problems, we leverage the context given to generate equations involving the slope of these lines. The challenge here is solving and making sense of the mod equations. We also sometimes get results with non-real values of the slope which we discard. We'll learn how to make sense of these results visually.
