Sam, if the line l is parallel to k, we know that the angle y is equal to the angle 2y-75. So we set y = 2y - 75, giving us y = 75.

Hi Sam. Well one angle is y, and the other is 2y-75, not 2x-75. So we set them equal to each other, and solve for y. If it contained another variable, we won't be able to solve for y.
y=2y-75
Shouldn't y = 2x-75 or another variable other than y? Logically it doesn't make sense.
Sorry for the multiple posts of the same Q, my cell phone farted.
