im not going to give u the answer but all you do is
step by step :
#1. D2- (-6*2),(0*2)=(-12,0)
(3*2), (-9*2)= (6,-18)
(12*2),(4*2)=( 24,8)
About 15.7, or 16 if you're looking for a whole number.

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:
