Answer:
46
Step-by-step explanation:
Since two of the arc measure 161 and 107, we can find the other two by finding a number that will equal it to 180.
[tex]161 + 19 = 180[/tex]
[tex]107 + 73 = 180[/tex]
19 and 73 are the missing arcs.
We then apply intersecting secants theorem,
[tex] \frac{19 + 73}{2 } = 46[/tex]
46 is the answer
