I have no idea how to do this :/

Answer:
301°
Step-by-step explanation:
First figure out arc XYZ, to do so, you need to find the interior angles
180 = 11w + (5w + 4)
180 = 16w + 4
Subtract 4 from both sides
176 = 16w
Divide both sides by 16
w = 11
Now plug that in for arc YZ
5(11) + 4 = 55 + 4 = 59
Therefore, arc YWZ will be 360 - 59 = 301
