    hi just stuck on a small problem during my research on allaboutcircuits. com (VOL II AC series resistor-inductor circuits) when they write Z total (5 + j0Ω) + (0 + j3.7699Ω) why are they using j? and i presume the right angled triangle missing one of its sides means phase angle but when they write the answer for Ztotal (5 +j3.7699Ω) or (6.262Ω phase angle 37.016 degrees) how the <snip> did they get the angle of 37.016 degrees i cant understand how they came up with that angle
