The question is: "In polar coordinates, what is the impedance of a circuit that has an admittance of 7.09 millisiemens at 45 degrees?"(adsbygoogle = window.adsbygoogle || []).push({});

The official answer is: "141 ohms at an angle of -45 degrees".

I don't understand this. 7.09 millisiemens is 141 ohms, and the positive phase angle indicates inductance, IOW a positive y value.

It seems the correct answer should be 141 ohms at an angle of 45 degrees, not -45 degrees.

Please help me understand this.
