Building the Broken Line (Ломаная)

To build the broken line (ломаная) CEFK according to the given specifications, we need to ensure that the length of each segment meets the specified criteria.

- Length of Segment CE: 8mm - Length of Segment EF: 14mm longer than CE - Length of Segment FK: 7mm shorter than EF

Calculating the Length of the Broken Line

To calculate the length of the broken line CEFK, we can use the given lengths of the segments and apply the principles of geometry to find the total length of the broken line.

The formula for calculating the length of a broken line is to sum the lengths of its individual segments. In this case, the broken line CEFK consists of three segments: CE, EF, and FK.

Let's denote: - Length of CE as x (given as 8mm) - Length of EF as x + 14 (14mm longer than CE) - Length of FK as (x + 14) - 7 (7mm shorter than EF)

Now, we can calculate the total length of the broken line CEFK by summing the lengths of its segments: Total length = CE + EF + FK Total length = x + (x + 14) + ((x + 14) - 7)

Calculation

Total length = x + (x + 14) + ((x + 14) - 7) Total length = 3x + 21

Result

The length of the broken line CEFK can be expressed as 3x + 21, where x represents the length of segment CE.

Conclusion

To find the specific length of the broken line CEFK, we would need the exact value of x, which represents the length of segment CE. Without this value, we can express the length of the broken line in terms of x as 3x + 21.
