Answer:
See below
Step-by-step explanation:
You have not provided the options.
But I will explain how you can work it.
Coterminal angles are two or more angles that have the same terminal side in standard.
If you want to find an angle that is coterminal with 98°, you keep adding or subtracting 360°.


Therefore 488°, 818°, -262° are examples of angles that are coterminal with 98°
A means the amplitude of the wave
2pi/B means the period of the wave
C means the place shift left of the wave
and D means the vertical shift of the wave
Note 2pi here means 2pi radian, not degrees.
If you have trouble understanding any of these vocabularies above, just ask in the comments, I will be happy to help.
