A Mathematical Major Arc is the larger of the two arcs formed when a circle is divided into two unequal parts. Therefore as a result the measure of a major arc is always more than 180° and the sum of the measures of the major arc and the minor arc is always equal to 360°

To find major arcs in a circle, first identify the endpoints of the arc on the circumference. Measure the angle subtended by the endpoints at the center of the circle; if the angle is greater than 180 degrees, the arc is a major arc. Alternatively, you can calculate the minor arc (the shorter arc between the two points) and subtract its length from the total circumference to find the length of the major arc. Major arcs are typically labeled with three points, including the endpoints and a point on the arc itself.
A whole circle is 360 deg so the major arc is 360-120 = 240 degrees.
