Question

find ef and de.

Explanation:

Step1: Calculate EF (distance of E to F)

$EF = |17 - (-11.3)| = |17 + 11.3|$

Step2: Compute EF value

$EF = 28.3$

Step3: Calculate DE (distance of D to E)

$DE = |-11.3 - (-17.6)| = |-11.3 + 17.6|$

Step4: Compute DE value

$DE = 6.3$

Answer:

$EF = 28.3$
$DE = 6.3$
