Answer:

La respuesta esta abajo

Step-by-step explanation:

Un triángulo es un polígono con tres lados y tres ángulos.

Se dice que dos triángulos son proporcionales si la razón de sus lados correspondientes está en la misma proporción.

de la pregunta, el lado AB es proporcional a DF, AC es proporcional a DE y BC es proporcional a FE

Por lo tanto, dado que ambos triángulos son proporcionales, entonces:

DE / DF = AC / AB

x / 10 = 21/15

x = (21/15) * 10 = 14
