If angle A, B, C of `DeltaABC` form an increasing AP, then Sin B =

If angle A,B,C of Delta ABC form an increasing AP,then sin B=

If angles A,B,C of a ABC form an increasing AP, then sin B=(1)/(2)(b)(sqrt(3))/(2)(c)1 (d) (1)/(sqrt(2))

If the angle A,B,C of a DeltaABC are in A.P then

The angles A, B and C of a DeltaABC are in A.P. If AB = 6, BC =7 ,then AC =
