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.


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


Thus,
represented in parametric form is:

Let me know if you need any clarifications, thanks!
