Jared is using a 100 ft rope to set up a kite-shaped area for food vendors. He has started roping off the area as shown below, a
Darina [297]

Answer:

The response is provided below

Explanation:

A kite is defined as a four-sided figure (quadrilateral) featuring two pairs of congruent adjacent sides.

From the illustration, it is clear that one set of congruent sides measures 30 feet each. Consequently, the amount of rope that has been utilized totals 60 feet, leaving 40 feet (100 - 60) available to finalize the kite's structure. Thus, 40 feet of rope would be required to create the second set of adjacent sides.

This indicates that the remaining adjacent sides will each measure 20 feet to ensure all rope is appropriately utilized.

NikAS [361]
Interacciones entre miembros del grupo
- interacciones con personas fuera del grupo
- interacciones con el entorno
Explicación:
La cultura es la herramienta más poderosa de cualquier sociedad. Es única para cada grupo y define a ese conjunto de personas. La cultura tiene la capacidad de modelar tres tipos de interacciones:
- interacciones entre los miembros del grupo
- interacciones con personas externas
- interacciones con el entorno
Las interacciones entre los miembros del grupo son generalmente positivas, ya que comparten la misma cultura y tienen numerosas similitudes. Un ejemplo podría ser la interacción entre dos vecinos.
Las interacciones con forasteros pueden ser variadas. Si existen ciertas similitudes culturales, es probable que se formen lazos, pero si hay diferencias marcadas, probablemente se genere conflicto. Un ejemplo podría ser la interacción entre un mexicano católico y un árabe musulmán.
La interacción con el entorno es esencial para cualquier cultura, y cada una tiene una relación especial con él, basada en sus características. Un ejemplo sería que los celtas consideraban sagrados a los árboles, y ciertos árboles, como el sauce, no podían ser cortados porque eran de alta importancia.
