According to the condition of the problem, it is specified that the AOB angle is unfolded, which means that it is equal to 180 degrees. The AOC angle is 50 degrees, which means it is an acute angle. In order to find the angle COB, it is necessary to subtract the acute angle AOC from the deployed angle AOB:
180 – 50 = 130 (degrees) – angle of COB.
The COB angle is an obtuse angle.
Answer: the COB angle is 130 degrees, the AOB angle is deployed, the AOC angle is acute, the COB angle is obtuse.
