Alrighty, so please bare with me, it's been a long time since I did this in school. Here's what I think each angle is:
Angle 1.) 102
Angle 2.) 78
Angle 3.) 102
Angle 4.) 78
Angle 5.) 145
Angle 6.) 35
Angle 7.) 145
Angle 8.) 35
A straight line equals 180 degrees so I subtracted 78 from 180 to get 102 degrees. An angle opposite another angle (If i remember correctly it's called an adjacent angle) is the same degree as the one opposite it.
Hope this helped! Hope I'm right! (:
