I was able to find the magnitude (328.85) but how is the phase angle 3.44°?? Idk the method when there's division involved. Thanks in advance

Well, there are two ways to deal with division, which are both standard:

1) Convert the fraction into real+imaginary part form by multiplying/dividing the conjugate of the denominator, making the denominator real. Then convert it to norm-argument form; or

2) Convert both the numerator and denominator into norm-argument form, then using index laws will tell you what the resulting norm and argument are.

The choice of which is up to you, really. In this case, given the numbers are not nice, I doubt it makes a difference.

EDIT: Though I'm curious as to how you've found the magnitude and not the argument.
