Answer:
Angle 2 = 0
angle 6 = 80
angle 9 = 100
angle 15 = 100
angle 16 = 80
Step-by-step explanation:
2 side by side angle should add up to 180 degrees
So, angle 1 + angle 2 = 180
100 + angle 2 = 180
angle 2 = 80 degrees
angle 3 is equal to angle 7 because of parallel lines
Angle 7 will also equal 100, and angle 6 is right beside it.
Angle 6 + angle 7 = 180
angle 6 = 80
Angle 9 and angle 15 are all equal to 100 because of parallel lines
Angle 16 + angle 15 = 180
Angle 16 = 80
