Answer:
200 is right answer and correct
Step-by-step explanation:
let a triangle named with ABC
angle A = 50
angle B = ?
Angle C = ?
one exterior angle = 110
exterior +interior angle = 180
angle B + 110 = 180
angle B = 180-110
angle B = 80
angle A+ angle B + angle C = 180
50+80+ angle C = 180
130+angle C = 180
angle C = 180-130
angle C = 50
hope it helps you
