Answer:

El pentágono tiene 5 diagonales.

El octágono tiene 20 diagonales.

El decágono tiene 35 diagonales.

Explanation:

El número de diagonales (d) de un polígono de n lados está descrito por la siguiente expresión:

d = \frac{n\cdot (n-3)}{2} (1)

A continuación, calculamos el número de diagonales para cada polígono:

(i) Pentágono (n = 5)

d = 5

(ii) Octágono (n = 8)

d = 20

(iii) Decágono (n = 10)

d = 35
