You can see that the section that contains the angle is exactly 1/3 of the circle. The answer to A is 1/3 because the circle is divided into 3 equal pieces. Now for B, since the total measure of a circle is 360°, divide that by 3 to get the measure for the given angle. 360 divided by 3 is 120, so the given angle is 120°
