Answer:

see explanation

Explanation:

Since the triangles are similar

(a)

The corresponding angles are congruent , that is

∠ A = ∠ D , ∠ B = ∠ E , ∠ C = ∠ F

(b)

The ratios of corresponding sides are equal, that is


(AC)/(DF) =
(BC)/(EF) , substitute values


(?)/(21) =
(8)/(24) ( cross- multiply )

24 ? = 168 ( divide both sides by 24 )

? = 7
