X=Y=130°
Step-by-step explanation:
Given:AB//CD
Then,y = 130°[vertically opposite angles] and x = y[alternate angles]
Hence,x=y=130°
Answer:
x =130° , y = 130°
Step-by-step explanation:
Let the 50° angle be a.
Let the 130° angle be b.
a] ∠x + ∠a = 180° --------( angles in linear pair )
∠x + 50° = 180°
∠x = 180° - 50°
∠x = 130°
b] ∠b = ∠y --------( vertically opposite angles )
∠b = 130°
∠y = 130°
