Answer:
66º
Step-by-step explanation:
From the picture we know that AB║CD. Therefore, the line BD is a transversal line between two parallels.
We know that in these cases, the alternate interior angles are the same.
In the picture, angle 1 and the angle that measures 66º are alternate interior angles. Therefore, angle 1 measures 66º as well.
∠1 = 66º
