Question

Name an angle supplementary to ∠COD
a. ∠AOE
b. ∠BOD
c. ∠COB
d. ∠COA

Answer 1

I believe the answer is d. angle COA

Answer 2

Option B. ∠BOD

Option D. ∠COA

Explanation:

we know that

Two angles are supplementary if their sum is equal to
`180` degrees

In this problem we have that

`m<COD+m<COA=180\°` -------> by supplementary angles

`m<COD+m<BOD=180\°` -------> by supplementary angles
