Degrees.
360 degrees = 100% so divide the angle's measure, in degrees, by 3.6.360 degrees = 100% so divide the angle's measure, in degrees, by 3.6.360 degrees = 100% so divide the angle's measure, in degrees, by 3.6.360 degrees = 100% so divide the angle's measure, in degrees, by 3.6.
a straight angle
It is a reflex angle.
A whole circle is 360 deg so the major arc is 360-120 = 240 degrees.
