How difficult it is to post the question in texts with attaching an image rather than just posting an skewed image?

Image
In triangle OAC, (x + x) = y ---> y = 2x
Also as OA = OB, in triangle OAB, y = (x + z) ---> 2x = (x + z) ---> z = x

Now, in triangle OAB, (x + y + (x + z)) = 180
--> (x + 2x + x + x) = 180
--> 5x = 180
--> x = 36

Answer : B
