4sqrt(9)A:B:C=2:3:4vec e uarr(A)/(B):(B)/(C):(C)/(A)=?

if A:B:C=2:3:4 , then (A)/(B):(B)/(C):(C)/(A) is equal to :

If A:B=4:9 and A:C=2:3 , find B:C and A:B:C

If vec (a),vec (b) and vec (c) are the position vectors of the points A(2,3,-4), B(3,-4,-5) and C(3,2,-3) respectively ,then |vec(a)+vec(b)+vec(c)| is equal to (A) sqrt(113) (B) sqrt(185) (C) sqrt(203) (D) sqrt(209)

For any triangle ABC, If B=3C, show that cos C=sqrt((b+c)/(4c)) and (sin A)/(2)=(b-c)/(2c)

If |vec a|=3,|vec b|=4 then a value of lambda for which vec a+lambdavec b is perpendicular to vec a-lambdavec b is : (9)/(16) (b) (3)/(4) (c) (3)/(2) (d) (4)/(3)

If vec a,vec b, and vec c are such that [vec avec bvec c]=1,vec c=lambdavec a xxvec b, angle, between vec a and vec b is (2 pi)/(3),|vec a|=sqrt(2),|vec b|=sqrt(3) and |vec c|=(1)/(sqrt(3)) then the angel between vec a and vec b is (pi)/(6) b.(pi)/(4) c.(pi)/(3) d.(pi)/(2)

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