How do you calculate the critical value of X^2 at the 5% level of significance in a chi squared? And how do you calculate the degree of freedom?

The textbook wording makes no sense and doesn't show it fully and I've read it over at least 10 times now to try to figure out how they get it.

Thanks for the help!
