Question

what are general rule for addition of vectors​

Answer 1

Vector addition is the operation of adding two or more vectors together into a vector sum. The so-called parallelogram law gives the rule for vector addition of two or more vectors. For two vectors and , the vector sum is obtained by placing them head to tail and drawing the vector from the free tail to the free head.

Answer 2

Answer:

Two vectors A and B are added by two different methods

Parallelogram Law

$a + b = \sqrt{ {a}^{2} + {b}^{2} + 2ab \cos(theta) }$

Triangle law
