Mathematics

In the given figure OA, OB are opposite rays and $\angle AOC+\angle BOD =90^{\circ}$, then $\angle COD$ is

$90^{\circ}$

SOLUTION
In the given figure, $\angle AOC + \angle BOD + \angle COD = 180^{\circ}$
Given, $\angle AOC + \angle BOD = 90^{\circ}$
Thus, $\angle COD = 180 -90 = 90^{\circ}$
