wow ok
B
First calculate BD using sine ratio in Δ BCD and the exact value
sin60° = , thus
sin60° = = = = ( cross- multiply )
2BD = 12 ( divide both sides by 2 )
BD = 6
-----------------------------------------------------------
Calculate AD using the tangent ratio in Δ ABD and the exact value
tan30° = , thus
tan30° = = = = ( cross- multiply )
AD = 6 ( divide both sides by )
AD = 6 → B
