Answer:
Option B. ∠BOD
Option D. ∠COA
Step-by-step explanation:
we know that
Two angles are supplementary if their sum is equal to [tex]180[/tex] degrees
In this problem we have that
[tex]m<COD+m<COA=180\°[/tex] -------> by supplementary angles
[tex]m<COD+m<BOD=180\°[/tex] -------> by supplementary angles
