How to Calculate Net Force in Vector Addition with Given Forces and Angles?

[Appelgater]

How do you find the net force in vector addition, for example if I have F1 = 64 N @ 30 degrees and F2 = 45 N @ 45 degrees and F3 = 78 N @ 330 degrees how would I go about finding the net force?

you can either draw it out or use vector components

Okay so the question says "What is the net force acting on an object that has the following forces on it", so how do I find that if

F1 = 64 N @ 30 degrees
F2 = 45 N @ 45 degrees
F3 = 78 N @ 330 degrees
