Question

Find the value of x in the given figure.​

Answer 1

let's see if i'm right.

check it

Answer 2

Answer:

BO=OA=OC (radius of the circle)

in∆AOB

BO=OA ( GIVEN)

<BAO=ABO=20 ( angle opposite to equal sides are also equal)

in∆ AOC

OC=OA ( GIVEN)

<OCA=<OAC (angle opposite to equal sides are also equal)

therefore <A = <BAO+<OAC

= 20+30=50°

x= 2×<A (the angle subtended by arc at the centre is double the angle subtended by it at any point on circle)

therefore x = 2×50

= 100°

hope it would be helpful for u!!!
