Final answer:
There is not enough information to determine the measure of x since we don't know the relationship between the angles 2x - 43 and 2x - 3.
Step-by-step explanation:
The problem does not provide enough information to accurately determine the measure of x because we do not have any information on the relationship between the angles 2x - 43 and 2x - 3. Typically, the missing information could be that they are supplementary, complementary or form some other geometric relationship that would allow us to solve for x. Without that, we cannot find the value of x from the given expressions alone.
