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:

Answer:
Hey there!
Angle x would be 62 degrees because angles in a triangle add to 180 degrees.
Let me know if this helps :)

a/x = x/4a
---
x^2 = 4a^2
x = 2a</span>
