In the unfolded angle of the AOB, the OC beam is drawn, the angle AOC = 130 degrees. Find the degree value of the angle of the COB.
The expanded angle is 180 °, so you can immediately mark it in the picture. The two corners that are formed are called adjacent. Adjacent angles add up to 180 °.
In order to find the second corner, you must:
180 – 130 = 50 ° – COB angle
Answer: Angle COB = 50 °
