To solve this problem, remember that the sum of adjacent angles is 180 degrees. In this task, when drawing a segment OC, we get two adjacent angles AOC and COB. Let us calculate what the degree measure of the COB angle is equal to, knowing that the AOC angle is 50 degrees.
180 – 50 = 130 degrees.
The AOC angle is an acute angle since its degree measure is less than 90 degrees – 50 degrees.
The COB angle is an obtuse angle, since its degree measure is greater than 90 degrees – 130 degrees.
Answer: 130 degrees.
