In 3:40 How you convert that complex rectangular form into simple 28-j22
Please recommend me a video

[@easystudyplus]

Its rectangle to polar conversion
If we have a+ib then it can be change to polar by
magnitude=sqrt(a^2+b^2) and angle =tan^-1(b/a)
Use this for 28-22j which is magnitude= sqrt(28^2+(-22)^2))=35.16
angle=tan^-1(-22/28) =-38.16 degree

[@yashasvikumar9244]

Sorry to bother you again sir but I know How 28-j22 is converted into 35.61 angle - 38.16 degree
But I donot understand How -j1I1+(j4+30+j40+80+J 60) I2 converted into I1=I2(28-j22)

Calculator take range from -π/2 to π/2 ,calculate using quadrant rule.

Here is the video for calculating angles

where did you get the I2, please explain

[@easystudyplus]

Solve the last step
(60-j80)(28-j22) I2 -j5 I2=50
