Answer:

Explanation:For two vectors A and B if Ā + B = © and A + B = C, then prove that Ā and B

are parallel to each other.​

Answer 2

Given that

vector a + vector b = vector c

Which means

C^2 = A^2 + B^2 + 2 A B cosx

Where x is the angle between vector a & vector b

But it is given that

A^2+B^2= C^2

Thus

C^2 = C^2 + 2 A B cosx

2A B cosx = 0

A &B are not zero therefore

Cosx = 0

X = 90 degree
