1) Calcula la diagonales de un poligono n lados. Heptágono: 2 puntos

ahrayia [7]

Answer:

El número de diagonales de un polígono de n lados se calcula mediante la siguiente fórmula:

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

Donde:

$d$ - Cantidad de diagonales del polígono.

$n$ - Cantidad de lados del polígono.

Bajo esta fórmula, tenemos los siguientes resultados:

a) El heptágono tiene 14 diagonales.

b) El octágono tiene 20 diagonales.

c) El eneágono tiene 27 diagonales.

d) El decágono tiene 35 diagonales.

e) El pentadecágono tiene 90 diagonales.

Explanation:

La cantidad de diagonales de un polígono se puede determinar mediante la siguiente ecuación:

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

Donde:

$d$ - Cantidad de diagonales del polígono.

$n$ - Cantidad de lados del polígono.

A continuación, calculamos la cantidad de diagonales de los siguientes polígonos:

Heptágono ( $n = 7$ )

$d = \frac{7\cdot (7-3)}{2}$

$d = 14$

El heptágono tiene 14 diagonales.

Octágono ( $n = 8$ )

$d = \frac{8\cdot (8-3)}{2}$

$d = 20$

El octágono tiene 20 diagonales.

Eneágono ( $n = 9$ )

$d = \frac{9\cdot (9-3)}{2}$

$d = 27$

El eneágono tiene 27 diagonales.

Decágono ( $n = 10$ )

$d = \frac{10\cdot (10-3)}{2}$

$d = 35$

El decágono tiene 35 diagonales.

Pentadecágono ( $n = 15$ )

$d = \frac{15\cdot (15-3)}{2}$

$d = 90$

El pentadecágono tiene 90 diagonales.

Why did the Chinese fail to foresee the threat that European expansion would pose for the rest of Asia and finally for China its

Anastasy [175]

The Chinese failed to foresee that the European expansion would rival their rise because the Chinese did not see the importance of voyages across oceans. The Europeans were out to discover new lands, resources and colonies. The Chinese were thinking about how to bring together their nomads.

37. Currently, rooftop solar panels produce only a fraction of the electricity used in the buildings on which they are installed

rewona [7]

Installing active solar energy systems on all available, unshaded rooftop

space and positioning them to face south.

<h3>What is a Solar system?</h3>

A solar system usually comprises of panels which help to collect solar

energy from the Sun and convert them to other forms of energy such as:

Heat energy.

Electrical energy.

The Passive system optimizes the use of heat or light directly from the sun

while the active systems converts the sun's energy into a more usable form

such as electricity. It is also best to position the panels to face south

because the Sun is found at this region thereby encouraging maximum

trapping of solar energy.
