If the diagonals AC = 8, BD = 6, m and N of the space quadrilateral ABCD are the midpoint of AB and CD respectively, and the angle between AC and BD is 90 degrees, then Mn is equal to
If the two right angles are 6 and 8, the length of the hypotenuse is 10, and the length of the hypotenuse is 5
The space quadrilateral ABCD, ab = CD = 8, m and N are the midpoint of BD and AC respectively. If AB and CD form an angle of 60 degrees, the length of Mn can be obtained
My calculation is Mn = 12.6
