1.	In the adjacent figure ( not to scale), O is the centre of the circle and `/_OBA =30^(@)`. Find `/_ ACB`. The following sentences ae the steps involved in solving the above problem. Arrange them in sequential order from the first to the last. (A) `/_OAB =30^(@), /_ OBA =30^(@)` `implies /_ AOB =180^(@) -30^(@)-30^(@) =120^(@)` (B) We known that `/_ ACD =("Reflex "/_AOB)/(2)=(240^(@))/(2)=120^(@)` (C ) Reflex `/_ AOB =240^(@)` (D ) `OA =OB` (radii) `implies /_ OBA= /_ OAB =30^(@)`.A. ABCDB. DCABC. DACBD. DCA
Answer» Correct Answer - C `(D),(A),(C ) ` and `(B)` is the sequenctial order.
