Final answer:
The value of x in the given figure is 53°.
Step-by-step explanation:
To find the value of x in the given figure, we can use the fact that a║b. This means that the angles formed by the transversal line are congruent. Since the angle labeled 53° is opposite to the angle we want to find, x, we know that x is also equal to 53°. Therefore, the answer is 53° (Choice D).
