Nigel is going from London, UK, to Moscow, Russia, by train. He goes 517 kilometers on a train from London to Paris, France. He takes another train 837 kilometers to Munich, Germany, and switches trains in Munich to ride 399 kilometers on a train to Vienna, Austria. His last train ride carries him 2,088 kilometers from Vienna to Moscow. Find his total distance by first rounding each distance to the nearest hundred kilometers before adding. Do not put units in your answer.

step-by-step explanation: 4 cause 2+2=4

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
