Hint :
Resolve the vectors in the x and y - axis direction with proper signs. That would make it easier to add them. Then, just add all the x - components of vectors and j - components of vectors.
Solution :
Vector A = (100 cos 45°) i + (100 sin 45°) j.
Vector B = (-100 cos 45°) i + (100 sin 45°) j.
Vector C = (100 cos 45°) i + (-100 sin 45°) j.
Add all these, and you will get your answer.
P.S.: Comment if you would like me to solve the complete answer or if you have any doubts.
