Hey guys

Hey guys, i'm doing a lab report and I'm having some trouble understanding the following equations.

my measurements:

I'm having some real problems trying to just use the equation.

What I have so far
az = [tan^(-1)](R/x)
given R = 2.68
L = 49.3
X = 2∏fL = 15.5

I just don't know how to work the complex numbers in the equation...
Let me know if you need more background

thanks guys

 

so I can get it down to-

(25.429<-80.19)sin(delta + 9.81) + 4.33<-160.38

But I don't know what to do with multiplying the complex number with SIN.

also I don't know if I did this bart correctly-
[V2^(-2)] / (Z^(2))
= 1072/[(15.73<80.19)(15.73<80.19)]
= 4.33<-160.38

What do you guys think?
