If `| vec a|=sqrt(3)\ | vec b|=2\ \ ` and ` vec a.vec b=sqrt(3,)\ ` find the angle between ` vec a` and ` vec b`

If vec(a) and vec(b) are vectors such that |vec(a)|=sqrt(3), |vec(b)|=2 and vec(a).vec(b)=sqrt(6) then the angle between vec(a) and vec(b) is

If |vec a|+|vec b|=|vec c| and vec a+vec b=vec c, then find the angle between vec a and vec b

If |vec a|=8,|vec b|=3 and |vec axvec b|=12, find the angle between vec a and vec b.

If vec a and vec b are two vectors such that |vec a|=4,|vec b|=3 and vec a*vec b=6. Find the angle between vec a and vec b

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 vec a and vec b are two vectors such that |vec a|=4,|vec b|=3 and vec avec b=6. Find the angle between vec a and vec b

If |vec a|=sqrt(26),|vec b|=7 and |vec a xxvec b|=35 find vec avec b.

If vec a + vec b = vec c and | vec a | = | vec b | = | vec c | find the angle between vec a and vec b

Let (vec a+vec b)*(vec a-b)=3 where |vec b|=1 and vec a*vec b=(3)/(2) then the angle between (vec a+2vec b) and vec a is

If | vec a | = sqrt (26), | vec b | = sqrt (7) and | vec a xxvec b | = 13 then vec a.vec b =
