Calculate the displacement of 3 different directions and distances?

Can someone please help me understand how to calculate the displacement of 3 different directions and distances?

130m due north, 50m due east, and then 40m due south how can i figure out the net displacement?

think of it like on graph paper where the center of the paper is (0,0). if you go straight up 130m you are at (0,130) if you then go straight right 100m you are at (100,130) then if you go left 250m you are at (-150,130). after adding/subtracting all the different movements you find your ending point. Use Pythagorean theorem to find the distance.
