In `triangleABC`, if `tanA : tanB : tanC = 1:2:3`, then `sinA:sinB:sinC` =?

In a triangleABC , If tan A: tan B : tan C = 3:4:5, then the value of sinA.sinB.sinC is equal to:

In a A B C , if tanA:tanB :tanC=3:4:5, then the value of sinA sinB sinC is equal to (a) 2/(sqrt(5)) (b) (2sqrt(5))/7 (2sqrt(5))/9 (d) 2/(3sqrt(5))

In a A B C , if tanA:tanB :tanC=3:4:5, then the value of sinA sinB sinC is equal to (a) 2/(sqrt(5)) (b) (2sqrt(5))/7 (c) (2sqrt(5))/9 (d) 2/(3sqrt(5))

In a A B C , if tanA:tanB :tanC=3:4:5, then the value of sinA sinB sinC is equal to (a) 2/(sqrt(5)) (b) (2sqrt(5))/7 (2sqrt(5))/9 (d) 2/(3sqrt(5))

In a A B C , if tanA:tanB :tanC=3:4:5, then the value of sinA sinB sinC is equal to (a) 2/(sqrt(5)) (b) (2sqrt(5))/7 (2sqrt(5))/9 (d) 2/(3sqrt(5))

In a triangle ABC tanA+tanB+tanC>=P then P=

If, in a triangleABC , tanA =1 and tanB=2, then: tanC=

tanA +tanB + tanC = tanA tanB tanC if

tanA +tanB + tanC = tanA tanB tanC if

In triangleABC , if angleC=90^(@) then tanA+tanB =
