As shown in the figure, C is the midpoint of line AB and D is the midpoint of line AC. given that the sum of the lengths of all line segments in the figure is 23, the length of line AC is______ ．
Let the length of line AC be x, then ad = X2, ab = 2x, DC = X2, DB = 32x, CB = x, ｜ x2 + X + 2x + x2 + 32x + x = 23, the solution is: x = 3713. That is, the length of AC is 3713. So the answer is: 3713

As shown in the figure, point C is the midpoint of line AB, and point D is the midpoint of line AC. given that the sum of the lengths of all line segments in the figure is 26, the length of line AC can be obtained
∵ point C is the middle point of line AB, point D is the middle point of line AC, ∵ ad = DC, AC = BC = 2ad, ab = 2Ac = 4AD, ∵ let ad = x, then CD = x, BC = AC = 2x, BD = 3x, ab = 4x, X + X + 2x + 2x + 3x + 4x = 26, 13X = 26, x = 2, AC = 2x = 4
