A diagram has vector A at 30 degrees above the positive x axis. length = 3 m
Vector B is ON the negative xaxis. length = 1 m
Vector C is ON the negative yaxis. Length is 2 m
What is the direction in degrees of vector a + vector B + vector C?

In x direction: 3 cos 30  1 = 1.6
In y direction: 3 sin 30  2 = 1.52 = .5
tan^1 (.5/1.6) =  17.35 degrees
or east 17.35 deg south
