3.If A:B=5:6 and B:C=4:7 then A:B:C=

If A:B=3:4 and B:C=2:3 , find A:B:C .

If A:B = 2:7 and B:C = 9:13, find A:C.

The angles A, B and C of a triangle ABC are in arithmetic progression. AB=6 and BC=7. Then AC is :

If a:b=3:5 and b:c=6:7 ,find a:b:c

(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=3B = 5C, find A:B:C.

(i) If A:B=2:3,B:C=4:5,C:D=6:7 FIND A:D

If in a /_\ ABC, a=6, b=3 and cos(A-B)= 4/5 then (A) C=pi/4 (B) A=sin^-1 2/sqrt(5) (C) ar(/_\ ABC)=9 (D) none of these

If origin is the centroid of a triangle ABC having vertices A(a,1,3), B(-2,b,-5) and C(4,7, c) , then the values of a, b, c are

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