Question

if O is the centre of circle find the value of x ​

Answer 1

Answer:

x=120°

Step-by-step explanation:

OB=OA (radius of the circle)

so, angle OBA=angle OAB

angle OAB=25°

similarly, OC=OA (radius of the circle)

so, angle OCA= angle OAC

angle OAC=35°

now, angle BAC=angle OAB+angleOAC

angle BAC=60°

as we now,

angle BOC or x = 2 angle BAC

so, angle BOC=2×60°

hence, x=120°
