Question

find the value of a and b in the given figure W=a X=135° Y=95° Z=a
​

Answer 1

Step-by-step explanation:

It can be observed that,

50º + x = 180º (Linear pair)

x = 130º … (1)

Also, y = 130º (Vertically opposite angles)

As x and y are alternate interior angles for lines AB and CD and also measures of these angles are equal to each other, therefore, line AB || CD.
