Question

To get from the post office to the library, you walked due north and then due east. The distance you walked east is 20 meters more than the distance you walked north. If you were able to walk directly from the post office to the library in a straight line, you would have walked 150 meters. Suppose x represents the distance you walked north. Which equation can be used to find x?
(Points : 1)
x2 + (x + 20)2 = 1502
x + (x + 20) = 150

x2 + (x + 150)2 = 202

202 = x2 1502
