Answer:
14
Step-by-step explanation:
The period is the x distance for one full cycle.
The 1st peak is at 1 and the second peak at 15
The period is 15 - 1 = 14
∆ on the Left;
x + 95 + 35 = 180°
x + 130 = 180°
x = 50°
In the middle:
50° + 63° + x= 180°
113° + x = 180°
x = 67°
∆ on the right:
67° + 85° + x = 180°
152 + x = 180°
x = 28°
