Juan mesura 1,75m y proyecta , en un momento dado , una sombra de 1,4m . Calcula la sombra que proyecta en este instante una farola de 4m de altura

Sagot :

Answer:

5m

Step-by-step explanation:

Calculamos usando la fórmula de la proporción

Sombra / Altura

Deje que la altura de la luz de la calle = x

1,4 m / 1,75 m = 4 m / x

Multiplicar cruzada

1,4 × x = 1,75 × 4

Dividir ambos lados por 1.4

x = 1,75 × 4 / 1,4

x = 5

Por lo tanto, la altura de la farola es de 5 m.
