Okay...I am posting a couple problems that I can't seem to get the answers that the book porvides. The two problems that I am struggling with are 6.24 and 6.25. Can someone work these and make sure that the answer in the book is correct. I know for a delta-connected load that the zero-sequence component is 0. I can't get the positive and negative-sequences (6.24). On 6.25 I am stuggling with getting the correct angle. The problems are attached.
