If `a:b = 5:8` and `c:b = 4:3` then `a:b:c` is equal to

If a+b+c=2,a^(2)+b^(2)+c^(2)=1 and abc = 3 then 1/a+1/b+1/c is equal to

If a ,b ,and c are in A.P., then a^3+c^3-8b^3 is equal to (a). 2a b c (b). 6a b c (c). 4a b c (d). none of these

In a triangle ABC , if cos A cos B + sin A sin B sin C = 1 , then a:b:c is equal to

If a : b = 3 : 5 and b : c = 4 : 7 , find a : b : c

If a : b = 3 : 4 and b : c = 8 : 9, find a : b : c

In a triangle ABC,if B= 30^@ " and " c = sqrt(3) b the A can be equal to

If A:B = 1:3 and B: C = 2:5. find A:C.

If A:B = 3:5 and B: C = 8:11, find A.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 Angle C is equal to

In a A B C ,A : B : C=3:5: 4. Then a+b+csqrt(2) is equal to a. 2b b. 2c c. 3b d. 3a
