If `|vec a| = 5, |vec a-vec b | = 8 and |vec a +vec b| = 10`, then `|vec b|` is equal to

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

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

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

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

If |vec a| = 2, |vec b| = 5 and |vec a xx vec b| = 8 then vec a . vec b

If |vec(a)| = 5, |vec(b)| = 6 and vec(a).vec(b) = -25 , then |vec(a) xx vec(b)| is equal to

vec u = vec a-vec b, vec v = vec a + vec b and | vec a | = | vec b | = 2 then | vec u xxvec v | is equal to

If | vec A | = 2, | vec B | = 5 and | vec A * vec B | = 8 then | vec A xxvec B | =

If vec a, vec b and vec c are perpendicular to vec b + vec c, vec c + vec a, vec a + vec b respectively and if | vec a + vec b | = 6, | vec b + vec c | = 8 and | vec c + vec a | = 10 then find the value of vec a + vec b + vec c

If |vec(a)| = 2, | vec(b)| = 5 and vec(a). Vec(b) = 8 , then |vec(a) - vec(b)| is
