Given |vec a|=10,|vec b|=2 and vec avec b=12, find |vec a xxvec b|

Given | vec a|=10 ,| vec b|=2 "and" vecadot vec b=12 ,"find"| vec axx vec b|dot

Given |quad vec a|=10 , |quad vec b|=2 and vec a *vec b=12 , find | vec a cross vec b| .

If two vectors vec a and vec b such that |vec a|=2, |vec b|= 3 and vec a.vec b = 4 , find |vec a - vec b|

If |vec(a)|=10,|vec(b)|=2 and vec(a).vec(b)=12 then find |vec(a)xx vec(b)| .

If |vec a|=5,|vec a-vec b|=8 and |vec a+vec b|=10, then find |vec b|

If |vec a|=10, and |vec b|=2 and vec a* vec b =12 , find angle between the two vectors

If | vec a|=8,| vec b|=3 and | vec a x vec b|=12 , find the angle between vec a and vec bdot

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|=2,|vec b|=1 and vec a*vec b=1, then find (3vec a-5vec b)*(2vec a+7vec b)
