To find the COD angle, we need to know the sum of all the angles of the triangle.
We know that the angles of a triangle add up to 180 degrees.
Therefore, since the problem statement says that the angle AOB = 53 °, and the angle BOC = 91 °, then we need to add these two angles and from (180) the sum of three angles, subtract the sum of the two angles.
1) 53 + 91 = 144;
2) 180 – 144 = 36.
Answer: The COD angle is 36 °.
