Question

What is the measure of
O A. 25°
O B. 295°
O C. 65°
O D. 115°

Answer 1

C. 65°

Explanation:

We Know

AB ≅ DC

Since ∠AOB and ∠DOC are vertical angles and they are congruent, meaning they are equal. So, the answer is C. 65°

Answer 2

Answer: C. 65°

Explanation:

Since we know that ∠AOB = 65°, as given by the picture, and that AB and DC are congruent, we know that ∠DOC is also equal to 65° since the arcs are congruent.
