3.14 - 3a Radians
Because 
180o = 3.14 radian
        
             
        
        
        
1) x=1
2) x=2.9
3) x=-10
4) x=?
5) IDK
        
             
        
        
        
90 80% disocunt so what you do is divide that then let me know what you got
        
                    
             
        
        
        
Use these equations when converting polar equations to parametric equations:


We know that  , so substitute that into both equations for x and y.
, so substitute that into both equations for x and y.


Now, replace  with any variable that you want to represent the parametric equations in. I'll use the standard variable,
 with any variable that you want to represent the parametric equations in. I'll use the standard variable, 


Thus,  represented in parametric form is:
 represented in parametric form is:

Let me know if you need any clarifications, thanks!
