#### Explanation:

**Rectangular #-># Polar: #(x, y) -> (r, theta)#**

- Find
#r# (radius) using#r = sqrt(x^2 + y^2)# - Find
#theta# by finding the reference angle:#tantheta = y/x# and use this to find the angle in the correct quadrant

Now we find the value of

To determine which one it is, we have to look at our coordinate

As you can see, it is on the negative side of the
