If `(b+c)/(5)=(c+a)/(6)=(a+b)/(7)` then `sin A:sin B:sin C=4:3:2`

In triangle ABC if (sin A)/(7)=(sin B)/(6)=(sin C)/(5) show that cos A:cos B:cos C=7:19:25

In Delta ABC, if a:b:c=3:4:5 , then sin A:sin B:sin C =

In Delta ABC , if a: b: c = 3: 4:5 then sin A : sin B : sin C =

In Delta ABC if a:b:c=3:4:5 then sin A:sin B:sin C is

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

Let a,b, c are the sides opposite to angles A, B , C respectively in a Delta ABC tan""(A-B)/(2)=(a-b)/(a+b)cot ""C/2 and (a)/(sin A)=(b)/(sin B) =(c)/(sin C), If a=6,b=3 and cos (A-B) =4/5 Valus of sin A is equal to

Let a,b, c are the sides opposite to angles A, B , C respectively in a Delta ABC tan""(A-B)/(2)=(a-b)/(a+b)cot ""C/2 and (a)/(sin A)=(b)/(sin B) =(c)/(sin C), If a=6,b=3 and cos (A-B) =4/5 Valus of sin A is equal to

Let a,b, c are the sides opposite to angles A, B , C respectively in a Delta ABC tan""(A-B)/(2)=(a-b)/(a+b)cot ""C/2 and (a)/(sin A)=(b)/(sin B) =(c)/(sin C), If a=6,b=3 and cos (A-B) =4/5 Valus of sin A is equal to

In Delta ABC , if ( sin A)/(4) = (sin B)/(5) = (sin C)/( 6) then the value of cos A +cos B +cos C =

If A+B+C= 180^(@) , then show that sin 2A+ sin 2B+ sin 2C =4 sin A sin B sin C .
