The total of the two angles is 218 degrees.
The image shows that angle AOB is 87, so you would subtract 87 from 218 to find BOC:
218 - 87 = 131 degrees.
The answer is C.
Answer:
m<BOC =131
Step-by-step explanation:
The sum of m< AOB and m<BOC is 218
m< AOB +m<BOC = 218
We know that angle AOB is 87
87+ m<BOC = 218
Subtract 87 from each side
87-87+ m<BOC = 218-87
m<BOC = 218-87
