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!

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°
