What calculator mode should i use to get answers like this?

I have question cosx=1:2
Im in radian mode which is where im supposed to be i know for sure, but i have a problem. 
Instead of getting an answer like my classmates- pie:3 
I get the sulotion of pie:3- 1.047
My teacher says we all have to be in radian mode, and i know that im on radian mode, and everyone else is too. but why do i get answers like this? Im not allowed to use answers like this please help me i have test in a fyu days.
My question is: how do i make my answers appear like pie:3 and not 1.047?? 
Thank you! 
(I have bad spelling because i dont live in english speaking country im sorry)
