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:
210.0
Step-by-step explanation:
you are rounding to the tens place so you look at the number before it is greater than 5 so you round up getting your answer of 210.0
B. I’m pretty sure. Since the arrow is pointing towards the S which is at the beginning.
