A矩形ABCD中,AB=6,AD=8.点M是AD的中点.求△AMC的面积.使用三角形的面积公式:A=(bh)/2,其中A是面积,b是底,h是高,给出方程A=(4⋅6)/2=(24)/2=12.故选A.与矩形的高和底相等的三角形面积是矩形的面积的一半,这意味着底的一半,相同的高的三角形面积是矩形面积的四分之一,所以我们有(48)/...

To solve the problem step by step, we will analyze the given information and apply the properties of circles, tangents, and triangles.Step 1: Understand the Configuration We have a rectangle ABCD inscribed in a circle with cent
题目的意思是长是宽的3倍，求m。所以根据这个列方程就可以了：由于长平行于x轴，所以长度就是用B的横坐标减去C的坐标，得长=6-（1-m）=m+5 同理宽度就是A的纵坐标减去B的，就是：（m+1）-（10-2m）=3m-9 所以有m+5=3*（3m-9）解得m=4 在...
