The vectors $a with not stretchy bar on top comma b with not stretchy bar on top comma c with not stretchy bar on top$ are equal in length and pair wise make equal angles. If $a with not stretchy bar on top equals l with not stretchy bar on top plus ȷ with not stretchy bar on top comma b with not stretchy bar on top equals ȷ with not stretchy bar on top plus k with not stretchy bar on top$ , then $c with not stretchy bar on top equals$

For such questions, concept of scalar product is important. When we take a dot product of two vectors, we get a scalar value. This is called as scalar product.
