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

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

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=0" and "abs(a)=3, abs(b)=5" and "abs(c)=7 then 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

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.

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