Question

use the figure below for questions 5 & 6. 9. if df = 61 and ef = 18, find de.

Explanation:

Step1: Identify the relationship

We know that $DF=DE + EF$.

Step2: Rearrange the formula to solve for $DE$

$DE=DF - EF$.

Step3: Substitute the given values

Given $DF = 61$ and $EF = 18$, then $DE=61 - 18$.

Step4: Calculate the result

$DE = 43$.

Answer:

$43$
