La base de un recogedor de basura mide 20.5 cm y su lado posterior 13.4 cm. ¿Cuánto mide la base de otro recogedor cuyo lado inferior mide 14.2 cm? *

21.72 cm

Explanation:

En este caso, es posible utlizar el teorema de Tales para relacionar los segmentos y así determinar la variable cuya medida es desconocida (es decir, la base del segundo recogedor de basura).  

De este modo:

20.5 cm / 13.4 cm = X / 14.2 cm  >>  

X = (20.5 cm x 14.2 cm) / 13.4 cm = X  

X = 21.72 cm
