For "Find NK" I used the Pythagorean theorem but I'm not sure if that is the right way. The last question I think I answered the first two parts correctly but I get so confused with arcs. Please help. Thank!

You got the first one correct....

 

I'll look at the second one in just a bit

Second one....good job, so far

 

As you found  QR and ST are equal so they span the same arcs...let the arcs they span  = x

 

 We have this equation 

 

360   -  QS - RT   =   QR  + ST

 

360  - 34 -  98  = x  +  x

 

228 = 2x     divide by 2

 

114°   = x  = measure of arc ST = measure of arc QR

 

And the measure of the span of arc XT  = (1/2)(arc ST)  = (1/2)(114°)  = 57°
