20 points for this cuz i don't know what the he|| I'm doing. Explanation would be nice but if not that's fine

Answer:
65° and 115°
Step-by-step explanation:
Supplementary angles add up to 180
So if you add A and B you get 180°
x + 50 + x + 100 = 180
2x + 150 = 180
2x = 30
x = 15
A = 15 + 50
A = 65
B = 15 + 100
B = 115
