Question

Hi, I am in physics I and they have the question of what is the angular displacement between 5s and 15s. 

At 15s, there is an angle of 50. But at 15 seconds, the angle is between 50 to 75.

I have attached the picture of the graph.

I understand that the angular displacement requires subtracting the final and initial angle and time from each other. But I really need to know which the angle is for 15s.
