Answer:
Explanation:
Since line A is parallel to line B, then angle 1 and angle D are alternate interior and are congruent. That means that angle 1 is 60. Angle 2 can be found by subtracting 60 + 58 from 180:
180 - 60 - 58 = 62. Now to find angle 3, we just subtract angle 1 and angle 2 from 180:
180 - 60 - 62 = 58 (which works out perfectly because angle 3 and angle E are congruent as we just found out!)
