Answer:
20, thats what is in your little box so that should be the answer
Given the equation:
![r=3-5\cos \theta](https://tex.z-dn.net/?f=r%3D3-5%5Ccos%20%5Ctheta)
Let's identify the type of polar graph for the equation.
To identify the type of polar graph, use the formula below to get the Cartesian form:
![(x^2_{}+y^2)=r(\cos \theta,\sin \theta)](https://tex.z-dn.net/?f=%28x%5E2_%7B%7D%2By%5E2%29%3Dr%28%5Ccos%20%5Ctheta%2C%5Csin%20%5Ctheta%29)
Thus, we have:
![(x^2+y^2)=3\sqrt[]{x^2+y^2}-5x](https://tex.z-dn.net/?f=%28x%5E2%2By%5E2%29%3D3%5Csqrt%5B%5D%7Bx%5E2%2By%5E2%7D-5x)
We have the graph of the equation below:
We can see the graph forms a Limacon with an inner loop.
Therefore, the type of polar graph for the given equation is a limacon with inner loop.
