In a triangle ABC, A=30° b=6. Let CB1 and CB2 are least and greatest integral values of the side a for which two triangles can be formed. It is also given that angle B1 is obtuse and angle B2 is acute angle. (A) |CB1-CB2|=1(B) CB1 + CB2 =9(C)area of triangle B1CB2= 6 + (3√7/2)(D)area of triangle AB2C= 6 + (9√3/2)
