Answer: 120 degrees.
Step-by-step explanation: A 90-degree angle would be a right angle. The segments would be perpendicular. In a 180-degree angle, the line would be flat. This angle is between these two angle measures. It appears quite close to a 120-degree angle such as the one shown below:
Because of this, I would estimate that the angle is around 120 degrees. It may be 130 degrees or 110 degrees but it appears to be approximately 120 degrees.
