In `Delta ABC` if `a:b:c=3:4:5` then `sinA:sinB:sinC` is

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 Delta ABC , if tan A : tan B : tan C = 3 : 4 : 5, then the value of sinA.sinB.sinC is equal to

[ln a Delta ABC,],sinA=4/5 then cosA=

If A+B+C=pi , then sinA-sinB+sinC=

In a Delta ABC, prove that (sinA+sinB)(sinB+sinC)(sinC+sinA)>sinAsinBsinC.
