60°

...............

do u want with explanation

that is isoceles triangle two sides and angles are also equal so angle OCA is 30°

and the next angle AOC ,in that triangle we know two sides so we can find the third side easily by using 30°+30°+x=180°, now that is 120°.

angle COB , we know that angle AOC is 120°,angleAOC and angle COB are linear pair so 120°+x°=180°

then we will get 60°
