Answer:

mAB = 30°

Step-by-step explanation:

mCD is the measure of angle 1 and mAB is the measure of angle 2. These angles are vertically opposite because they are formed by intersecting lines and they are on opposite sides.

Vertically opposite angles have the same measure, so:

mAB = mCD

mAB = 30°

Therefore, the measure of AB is 30°
