Explanation:

Since no additional information about the angle 'a' or the figure is given in the text part of the question, we assume we are to use general knowledge of common - angle measures. A straight - line angle is 180 degrees, a right - angle is 90 degrees. Without seeing the figure, we can't be sure, but if it's a standard multiple - choice question about common angles and no other context, we need to consider typical angle values.

Answer:

No answer can be determined as the figure is not described well enough to know which of the given angle measures is correct for angle 'a'.
