Question

На відрізку АВ завдовжки 23 см позначили точки СД так що АС =15 см ДВ =12 см. чому дорівнює довжина СД

Answer 1

Щось тут не правильно
мала б сума AC додатись з ДВ і потім від АВ відняти суму попередніх

Answer 2

Given Information

We are given a line segment AB with a length of 23 cm. Points C and D are marked on the line segment such that AC = 15 cm and DV = 12 cm. We need to find the length of CD.

Solution

To find the length of CD, we can subtract the lengths of AC and DV from the total length of AB.

The length of CD can be calculated as follows: CD = AB - AC - DV

Substituting the given values: CD = 23 cm - 15 cm - 12 cm

Simplifying the equation: CD = 23 cm - 27 cm

Calculating the result: CD = -4 cm

Therefore, the length of CD is -4 cm.

Please note that a negative length is not possible in this context. It is likely that there is an error in the given information or the calculations.
