solution:
since angle ACB = 60°,
so angle AOB = 60×2 = 120°
(angle subtended by an arc at the center is twice the angle subtended by same arc at any other point of circle)
since,angle AOB + angle AOB(reflex) = 360°
(complete angle is 360°)
therefore,
120° +angle AOB (reflex) = 360°
angle AOB (reflex) =360°-120°=240°
so x=240°

geetika3:
no how it can be
angle aob will be 120° by theorem
and a complete angle forms 360°
so we will subtract 120 from 360
if we draw those lines a&b to a point d on arc.Then angle 60 is supplementary to angle c.So it becomes 120° .After then i think angle o=angle d
i didn't understand
ok i got it TQ
but why to do such construction when it can be done with this simple method
your welcome
plz mark as brainliest
