Hi Mate!!!
In Trangle ADC
Tan ( 60) = 20√3 / AD
√3 = 20√3 / AD
AD = 20
In Trangle ABD
Sin ( @ ) = AD / AB
Sin (@ ) = 20 / 40
Sin (@ ) = 1/ 2
Sin ( @ ) = Sin ( 30 )
@ = 30
@ = theta
Hope it helps

in triangle ADC we have
sin60° = DC/AC = 20√3/AC
√3/2 = 20√3/AC
AC = 40cm = AB
since here AC = ab it is an isosceles triangle
so
angleABD = angleACD
in triangle ADC
angleADC = 180-(90+60) = 30°
hence
angleABD = angleACD = ¤ = 30°
sin60° = DC/AC = 20√3/AC
√3/2 = 20√3/AC
AC = 40cm = AB
since here AC = ab it is an isosceles triangle
so
angleABD = angleACD
in triangle ADC
angleADC = 180-(90+60) = 30°
hence
angleABD = angleACD = ¤ = 30°
