Angles 1 and 2 form a linear pair. A linear pair of angles is supplementary. The sum of the measures of two supplementary angles is 180 degrees. If angle 2 is twice the measure of angle 1, let represent the measure of angle 1. Then must represent the measure of angle 2. Since the sum of the measures of these two angles is 180 degrees:
