Since the lines are parallel, the opposite angle is always the same, and since 48 degrees was the smaller bottom angle, the upper smaller angle is also 48 degrees. The line's total angle is 360 degrees, so 48 + 48 is 96, and 360 - 96 is 264, and then 264 divided by 2 is 132, so the larger angles on both intersections are 132 degrees.
