请翻译As shown in the following diagram,there is a triangle ABC.Now we extend the length of Side AB to Point D,which makes BD=ab; while we estend the length of Side AC to point E,which makes CE=2AC;THUS we can get a bigger triangle ADE.Now please calculate the area ratio of Tr...
Introduction:A contrast column chartuses forward and backward columns to display the numerical comparison between categories. One axis of the chart shows the category being compared, while the other axis represents the corresponding scale value. ...
