The unfolded angle is 180 °. To answer the question of the problem, you need to know the value of the angle AOD or the value of the angle COB.
1). Let us determine what the degree measure of the angle AOD is equal to.
180 – 120 = 60 °.
2). Let’s calculate the degree measure of the angle DОС.
130 – 60 = 70 °.
Answer: The DOC angle is seventy degrees.
