it is very important that wold is not the first woman

so,60

Answer 2

Answer:

Step-by-step explanation:

∠AOB  = 60° where o is the centre of a circle and angle ACB=30°

Step-by-step explanation:

o is the centre of a circle

∠AOB  = Angle subtended by arc/Chord  AB at Center

∠ACB = Angle subtended by arc/Chord  AB  at arc segment

Angle subtended by arc/Chord  AB at Center = 2 (Angle subtended by arc/Chord  AB  at arc segment)

=> ∠AOB  =  2 ∠ACB

=> ∠AOB  =  2 * 30°

=> ∠AOB  = 60°
