You need two theorems.
1) If two cords of a circle intersect at an interior point the measure of the angles formed is equal to the average of the two intercepted arcs.
2) The measure of an arc subtended by a central angle is equal to the measure of the central angle.
Thus what us the average of \(24^o~\&~122^o~?\)
