How many angles a that are coterminal to -60 degrees exist such that −2000°

 

Okay so I can't understand this because I keep getting 11 angles, but sometimes I get 12?

 

For my positive angles I have: 

 

-60+360, -60+720, -60+1080, -60+1440, -60+1800

 

For my negative angles I have: 

 

-60-360, -60-720, -60-1080, -60-1440, -60-1800

 

This is 10, but I guess my two questions is if this is correct so far, and if the same angle can be counted as a coterminal angle. Is that possible?

 

That would bring it up to the 11 I keep getting. 

 

Someone please help!!!

I don't understand what you mean when you wrote "exist such that -2000o".

Can you explain this part?

Oh my im so sorry! I think it was a typo. I meant to say: 

 

"...exist such that -2000 deg < a < 2000 deg"

I believe that an angle can be classified as coterminal to itself, giving 11 answers.
