How to convert rectangular to polar?
x²=y(8-y)

The Polar form  is  r = 8sin θ

Step-by-step explanation:

Explanation:-

The Polar co-ordinate system is a two - dimensional co-ordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. The reference point is called the poleThe ray from the pole in the reference direction is the polar axis

Polar co-ordinates

              x = r cos θ    and      

               y=r sin θ      

now      

               tan θ =

Now given equation x²=y(8-y)

                                 

                                    ...(i)

now The equation(i)  convert to polar

                                      r² = 8(r sin θ)

                                      r = 8sin θ

Conclusion:-

The Polar form is  r = 8sin θ

     

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

Sorry i really need my points
