Answer:

DE ≈ 3.9 cm

Explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion, that is


(DE)/(AB) =
(DC)/(AC) ( substitute values )


(DE)/(8.4) =
(8)/(17.2) ( cross- multiply )

17.2 × DE = 8.4 × 8 = 67.2 ( divide both sides by 17.2 )

DE = 3.9 cm ( to the nearest tenth )
