Force is a vector. We get force from time derivative of momentum and momentum is a vector because velocity is a vector which is time derivative of displacement which is again a vector. In simple words-force has both magnitude and direction and hence it is a vector quantity.
Simply add the two north vectors and use the Pythagorean theorem to add the east vector. Take the sum of all the vectors. That's the resultant force. A force equal in quantity but oriented in the exact opposite direction is the equilibrant force.
