1. △edc ~ △ekj

Explanation:

Step1: Set up similarity proportion

$\frac{ED}{EK} = \frac{EC}{EJ}$

Step2: Substitute known values

$\frac{84}{70} = \frac{72}{EJ}$

Step3: Cross-multiply to solve

$84 \times EJ = 70 \times 72$
$EJ = \frac{70 \times 72}{84}$

Step4: Calculate final value

$EJ = \frac{5040}{84} = 60$

Answer:

60
