Question

find the missing lenght of de.

Explanation:

Step1: Identify the total length and known segment

The total length from \( C \) to \( E \) is \( 30 \), and the length from \( C \) to \( D \) is \( 14.2 \).

Step2: Subtract to find \( DE \)

To find \( DE \), we subtract the length of \( CD \) from the total length \( CE \). So, \( DE = CE - CD \).
Substituting the values, we get \( DE = 30 - 14.2 \).
Calculating this, \( 30 - 14.2 = 15.8 \).

Answer:

The missing length of \( DE \) is \( 15.8 \).
