1. The problem statement, all variables and given/known data

Circuit diagram:

Calculate the phasor mesh currents, I1 and I2.

2. Relevant equations

KVL/Mesh Current analysis with phasors/complex numbers.

3. The attempt at a solution

Mesh 1: (-550@0deg) + j75(I1) + 30(I1 - I2) - j40(I1) - j24(I2) = 0

Mesh 2: (600@-30deg) + 30(I2 - I1) + j50(I2) + 80(I2) - j24(I1) = 0

(30 + j35)I1 - (30 + j24)I2 = 550

-(30 + j24)I1 + (110 + j50)I2 = (-600@-30deg)

I got:

I1 = (9.45503221553 @ -38.8333374187 degrees) A

I2 = (2.79176352576 @ 93.1719060416 degrees) A

This problem was even demonstrated in class. Yet the homework site keeps telling me I'm wrong. I don't see where I've made a mistake...?
