Let `|vec a| = |vec b| = |vec a-vec b| = 1`. Then the angle between `vec a and vec b` is

If |vec a|=|vec b|=|vec a-vec b| then the angle between vec a and vec b is

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

vec a + vec b + vec c = vec 0, | vec a | = 3, | vec b | = 5, | vec c | = 7 then angle between vec a and vec b is

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| = |vec A|-|vec B| , then the angle between vec A and vec B is

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 xxvec b|=|vec a*vec b|, then find angle between vec a and vec b

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

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+vec B|=|vec A|=|vec B|, then the angle between vec A and vec B is
