[vec a+vec b,vec b+vec c,vec c+vec a]=2[vec a,vec b,vec c]

vec a+vec b+vec c=vec 0,vec |a|=3,|vec b|=5 and |vec c|=7 find the anglebetweeen 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

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

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

If vec a+ vec b+ vec c= vec0,\ vec|a|=3,\ | vec b|=5\ a n d\ | vec c|=7 find the anglebetweeen vec a\ a n d\ vec b

Vector vec a , vec b and vec c are such that vec a+ vec b+ vec c= vec0 and |a|=3,| vec b|=5 and | vec c|=7. Find the angle between vec a and vec b .

Let vec a , vec b , vec c are three vectors , such that vec a + vec b + vec c = vec 0 .If , |vec a|=3 , |vec b|=4 and | vec c|=5 , then the value of, |vec a+vec b|^(2) + |vec b-vec c|^(2) + |vec c+vec a|^(2) , equal to :

If vec a, vec b, vec c are three vectors such that vec a + vec b + vec c = vec 0 and |vec a| = 2, |vec b| = 3, |vec c| = 5 , then the value of vec a . vec b + vec b . vec c + vec c . vec a =

[vec a + vec b, vec b + vec c, vec c + vec a] = 2 [vec a, vec b, vec c]
