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

If a + b + c = 0 and |a| = 3, |b| = 4 and |c| = sqrt(37) the angle between a and b is

If a+b+c=0 and |a|=sqrt(37),|b|=3, |c|=4 then the angle between b and c is

If a + b + c = 0 and |a| = 1, |b| = 1, |c| = sqrt3 ,then the angle between a and b is

Ifa,b,c are vectors such that a + b + c = 0 and | a | = 7, | b | = 5,| c | = 3, then the angle between c and b is a) pi//3 b) pi//6 c) pi//4 d) pi

Read the following information carefully and answer the questions given below a+b+c= 0 such that |a|= 3, |b|=5 and |c|=7 What is the angle between a and b?

if a+b=c and |a|=4,|b|=6,|c|=8 then angle between a&b is
