Is There a Mistake in Calculating Vector Components and Angles?

[alingy1]

There seems to be problem with the answer to this problem. Weirdly, they get that the x component of F1 is 3N!

Then, when they end up calculating the direction in C, they get 9.5°. I get 9.16°.

Am I the one going crazy? This is fairly straight-forward!

From the 31 "they"calculate, I conclude that F1x is 7N in their calculations. (I get 31.4)
You and I get 9.16 degrees, perhaps "they" write it as 9 degrees 5 minutes ? (I 9° and 6')

Wouldn't worry too much about this, you're no crazier than I am!
