Final answer:
The length of segment DE is found by subtracting CD from CE. Given CE = 18 meters and CD = 12 meters, the length of DE is 6 meters.
Step-by-step explanation:
You want to find the length of segment DE on line segment CE, given that CE = 18 meters and CD = 12 meters. Since D is a point on line segment CE, the segments CD and DE add up to the total length of CE.
To find DE, use the fact that the entire segment CE is the sum of segments CD and DE. So we have the equation:
CE = CD + DE
Now substitute the known values into the equation:
18 = 12 + DE
Solve for DE by subtracting 12 from both sides of the equation:
DE = 18 - 12
DE = 6 meters.
Therefore, the length of segment DE is 6 meters.
