Thank you! It makes more sense now!
Thank you for your help! Could you explain how you got that? I wasn't really sure if you could separate the magnitude of z+w to the sum of two magnitudes.
Just figured it out! Each concentric circle has a radius of 1, so the x coordinate for A1 would be 2, and the y coordinate is the angle θ based off the unit circle so in this case for A1 it would be π6.
