ok so I am not sure how else to do this problem, my answers look similar to those in the book. where they have β=52.5 $\alpha=121$ $\gamma=53.1$, I feel like the book is wrong because i dont see any other way to solve this problem.

Heres how I solved for the angles

The gammas are the same so I am unsure where I went wrong.
