[" 1.If "vec a+vec b+vec c=0" and "|vec a|=3,|vec b|=5,|vec c|=7" then find the "],[" angle between "vec a" and "vec b]

If vec a+vec b+vec c=0 and |vec a|=3,|vec b|=5,|vec c|=7, show that the angle between vec a and vec b is 60^(@)

If vec a + vec b + vec c = 0 and |vec a|= 3, |vec b| = 4 and |vec c| = sqrt37 , then the angle between vec a and vec b is

If vec a+vec b+vec c=0 and |vec a|=3,|vec b|=5 and |vec c|=7, show that the angle between vec a and vec b is 60^(@) .

Vector vec a,vec b and vec c are such that vec a+vec b+vec c=vec 0 and |a|=3,|vec b|=5 and |vec c|=7. Find the angle between vec a and 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 .

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

vec a + vec b + vec c = vec 0, | vec a | = 3, | vec b | = 5, | vec c | = 9 find the angle between vec a and vec c

If vec a+ vec b+ vec c=0 and | vec a|=3,\ | vec b|=5 and | vec c|=7 , show that the angle between vec a and vec b is 60^0 .

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