SUMMARY
To find the third vector C in the equation A + B + C = 0, where vectors A and B each have a magnitude of 5 and form a 30-degree angle, one must first calculate the resultant vector of A and B. This is achieved using vector addition principles, specifically the law of cosines and the law of sines. The magnitude of vector C will equal the magnitude of the resultant vector of A and B, and its direction will be opposite to that resultant vector to satisfy the equation.
