Final answer:
Given the expression "7x + 11" for an angle measure and without additional context, the measure of the angle in expression form would be 7x + 11 degrees.
Step-by-step explanation:
The measure of the angle indicated in bold, "7x + 11", does not provide enough information to determine a specific numerical value, as we would need more context or a specific equation relating to the angle. However, given the available options, the measure in expression form would be 7x + 11 degrees, as no operations are specified to be performed on the expression. Answer choice (a) 7x + 11 degrees is the best fit for the information provided in the question.
