b. what is its measure in degrees?

Explanation:

For the question "What is its measure in degrees?" (related to straight angle):

Step1: Recall straight angle definition

A straight angle is formed by a straight line, and by definition, it measures 180 degrees.

To draw a straight angle, draw a straight line and mark a point on it. The two rays (formed by the point and the line segments) form a straight angle. We know it's a straight angle because it forms a straight line, and by the definition of a straight angle, an angle that is a straight line measures 180 degrees (or because it is formed by two opposite rays forming a linear pair, and the sum of angles in a linear pair is 180 degrees).

Answer:

180 degrees
