Answer 2

Answer:

210°

Step-by-step explanation:

Because angle C is adjacent to angle A and angle A and angle X form a linear pair. Sum of a linear pair is always 180°. When we subtract 80 from 180 we get 100°.Angle D is equal to angle B and they are adjacent. Adjacent angles are equal. Angle D and Y will form a linear pair. So when we subtract 180 from 70 we get 110°. So 100+110=210°
