The OC beam divides the angle AOB = 120 degrees into two angles so that one of them is 30 degrees less than the other. Find the AOC angle and the BOC angle.
The OC beam divides the AOB angle so that the sum of the AOC left and the COB angle is 120 °. Let one of the angles be equal to X. Then X + (X + 30 °) = 120 °. So X = 45 °, and the other angle is 75 °.
