Since angle O is 128°, we know that the opposite angle must also be 128°. This is because angles that are opposite each other in a circle are supplementary, meaning they add up to 180°.
Since angle x is opposite angle O, we can conclude that angle x is also 128°.
Therefore, the value of x is 128° (Answer: 256).
