G為出發點
兩個城市分別離她8 跟10公分
直角三角形求斜邊長
八平方加十平方等於164
13的平方為169最接近
所以選她

On a map Town G is 10 centimeters due east of Town H and 8 centimeters due south of Town J. Which of the following is closest to the straight-line distance, in centimeters, between Town H and Town J on the map?

是說G 是在H的東邊10cm, 在J的南邊8cm
問H跟J的距離為幾cm(最相近值)?
你把圖畫一畫, 就會發現這是要求直角三角形的斜邊=開根號(8^2+10^2)=13(接近值)
