Answer: In the given figures, if l and m are parallel, it means that they are always equal. Therefore, if l = m, then the value of x in each of the following X+50 is x = 50.
This is because, if l and m are parallel, that means that the measure of the angle between them is always equal to zero. Therefore, the angle between l and m is 0, and that's why the lines are parallel. So, since l = m, the value of x in each of the following X+50 is x = 50.
