    Can you please have a look at Q3 part (iv) in the attached file.
    Not sure if i have the right answer!

    Eulers notation:

    Is = I1 +I2 = 1.69 + j0.719 + 2.39
    = 4.08 + j0.719
    = 4.14 A

    Phase lag = 10°

    Any help is appreciated

    you were almost there but forgot the j operator for the inductance term

    Is = I1 +I2 = 1.695 + j0.719 -j2.39
    = 1.695 -j1.67
    = 2.379 A @ -44.57°

    Phase lag = 44.57°
