See circuit in file attached (and problem statement).
I first found the voltage across the inductor  I * Z = 5.6*<28.
Next I simply used V1  delta V = V2. I found that 100  5.6*cos(28)+ i*sin(28)*5.6 = ... and simplified the expression and brought back to phasor notation. I did not get the right answer...at all!
Note that my answer in the image attached was my first attempt. The way I solved above gave a different answer.
Any help as to where I am going wrong? Thanks!
