What are coterminal angles?
If you graph angles x = 30o and y = - 330o in standard position, these angles will have the same terminal side. See figure below.
Coterminal angles Ac to angle A may be obtained by adding or subtracting k*360 degrees or k* (2 Pi). Hence
Ac = A + k*360o if A is given in degrees.
or
Ac = A + k*(2 PI) if A is given in radians.
where k is any negative or positive integer.
Example 1: Find a positive and a negative coterminal angles to angle A = -200o

I hope that's help but , please help me know if you have question
Answer:
Hotdogs cost $2 and potato crisps $0.75.
Step-by-step explanation:
Let the hotdogs cost $h and the crisps $p
5h + 2p = 11.5
3h + 5p = 9.75
Multiply the first equation by -5 and the second by 2:
-25h - 10p = -57.5
6h + 10p = 19.5 Adding these 2 equations:
-19h = -38
h = $2.
Substitute h = 2 into the first equation:
5h + 2p = 11.5
10 + 2p = 11.5
2p = 1.5
p = $0.75.
Answer: 360 degrees
Step-by-step explanation:
Multiply by 1/3. 360(1/3)=120.
