Answer:
Angle 1 = 80 degrees
Angle 2 = 80 degrees
Step-by-step explanation:
The angle above angle 1 is an alternate exterior angle to 100 degrees. A straight line is 180 degrees total, so solve 180 - 100, to get 80 degrees for angle 1.
Using the same property, angle 2 will be 80 degrees as well.
Hope it helps!
