In a `deltaABC`, if `tan A: tan B :tanC= 3:4:5`, then the value of `sin A :sin B: sin C` is equal to

In a ABC, if tan A:tan B:tan C=3:4:5 then the value of sin A sin B sin C is equal to (a) (2)/(sqrt(5)) (b) (2sqrt(5))/(7)(2sqrt(5))/(9) (d) (2)/(3sqrt(5))

In Delta ABC, if tanA: tan B: tan C=1:2:3 , then sin A: sin B: sin C =

In /_ABC, if tan A:tan B:tan C=1:2:3, then sin A:sin B:sin C=?

If tanA = 3/4 "and" tan B = -5/12,"then the value of" sin(A + B) "is equal to"

In DeltaABC, tan B + tanC=5 and tan AtanC=3 , then

In DeltaABC, tan B + tanC=5 and tan AtanC=3 , then

In DeltaABC, tan B + tanC=5 and tan AtanC=3 , then

In DeltaABC, a = 3, b = 4 and c = 5 , then value of sinA + sin2B + sin3C is
