If `A : B = 3 : 4` and `B : C = 6 : 5`, then `A : (A + C)` is equal to:

(a) If A : B = 3 : 4 and B : C = 6 : 7 , find : (i) A : B : C (ii) A : C (b) If A : B = 2 : 5 and A : C = 3 : 4 , find : A : B : C .

If a : b = 3 : 2 and b : c = 4 : 5 , find a : c

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

In a DeltaABC , if a = 4, b = 5 , c = 6 then angle C is equal to

If a: b= 2: 3, b: c= 4: 5 and c: d= 6: 7 , find : a: b: c:d .

Let 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

If a : b=4:5 and b : c=2:3, then a : c (a) 4:3 (b) 8: 15 (c) 8:9 (d) 5:3

If a+b+c=0, then a^(3)+b^(3)+c^(3) is equal to

Add : a - 3b + 3, 2a + 5 - 3c, 6c - 15 + 6b
