Really sorry if this is incorrect, I had this question on my Lesson 16 test, and I don't know if it's correct or not...
Answer:
a) 
b) 
Step-by-step explanation:
Polar coordinates are represented as:
, where 'r' is the length (or magnitude) of the line, and '
' is the angle measured from the positive x-axis.
in our case:

to covert the polar to cartesian:


we can plug in our values:


the Cartesian coordinates are:


(b) to convert (x,y) = (6.06,-3.5)
we'll use the pythagoras theorem to find 'r'



the angle can be found by:




to convert radians to degrees:

writing in polar coordinates:

180-130=50
180-96=84
angles in a triangle add up to 180
50+84=134
180-134=46
x=46 degrees
