An isosceles `DeltaABC` is right angled at B. D lies inside `DeltaABC`. P and Q are resectively the base of perpendiculars drawnon side AB and AC of `DeltaABC` from point D. If AP = a cm, AQ = b cm and `angleBAD=15^(@)`, then what will be `sin75^(@)`?

`(2b)/(sqrt(3)a)`

`a/(2b)`

`(sqrt(3)a)/(2b)`
