The easiest way to do this is to compute the x and y components of the vectors and add them (add all the x components to each other, the same with the y). [The x components are A*cosø and the y components are A*sinø where A is the magntitude and ø the angles.] You will get the x and y components of the sum vector. Get the magnitude of the sum vector from the square root of the sum of the squares of the x and y components, and the angle from arctan(y comp / x comp).

A graphical method for vector addition is to simply draw them end to end with their correct directions and lengths.
In this case, the first vector goes up and to the right, the second one goes up and to the left, and the third goes down and to the right. Since they are all the same length, it's easy to see where the endpoint is.
