MCQ
Mark $(\checkmark)$ against the correct answer.In the given figure, two straight lines $AB$ and $CD$ intersect at a point $O$ and $\angle\text{AOC}=50^\circ$. Then, $\angle\text{BOD}={ ?}$
  • $40^\circ$
  • B
    $50^\circ$
  • C
    $130^\circ$
  • D
    $60^\circ$

Answer

Correct option: A.
