Answer:

La distancia desde el supermercado hasta la puerta del rascacielos es de 585,29 metros

Step-by-step explanation:

Dado que la altura del ático = 527 metros

El ángulo de elevación de la vista = 42 °

Tomamos la posición de la persona que ve el rascacielos en el supermercado, el ático del rascacielos y la base del rascacielos directamente frente a la persona, formando los vértices de un triángulo rectángulo ABC, respectivamente.

Por lo tanto;

AB = Línea de visión desde la persona hasta el ático.

BC = La altura del rascacielos = 527 metros

AC = La distancia desde el supermercado hasta la puerta del rascacielos.

De lo cual se nos da, ∠BAC = 42 °

Por lo tanto, ∠ACB = 90 ° y el ángulo de depresión desde el ático del rascacielos hasta la persona en el supermercado ∠ABC = 180 ° - 90 ° - 42 ° = 48 °

De la regla senoidal, tenemos;

\dfrac{BC}{sin(\angle BAC)} =\dfrac{527}{sin(42^{\circ})} = \dfrac{AC}{sin(\angle BAC))} = \dfrac{AC}{sin(48^{\circ})}

Lo que da;

AC = \dfrac{527 \times sin(48^{\circ}) }{sin(42^{\circ})}= 585.29 \ metros

Por lo tanto;

La distancia desde el supermercado hasta la puerta del rascacielos = 585,29 metros.

To cover A rectangle region of her yard penny needs atleast 170.5 square feet of sod. The length of the region is 15.5 feet. Wha
stiks02 [169]
The area needed is at least 170.5 ft².

Let w  =  the width of the rectangular area.
Because the length is 15.5 ft, therefore the calculated area should be at least 170.5 ft². That is
(15.5 ft)*(w ft) ≥ 170.5 ft²
w ≥ 170.5/15.5
w ≥ 11 ft

Answer:  w ≥ 11 ft

*How does placing the Declaration of Independence in its historic context change its meaning?
Strike441 [17]

Answer:

Declaration of Independence was designed for multiple audiences: the King, the colonists, and the world. It was also designed to multitask. Its goals were to rally the troops, win foreign allies, and to announce the creation of a new country. The introductory sentence states the Declaration’s main purpose, to explain the colonists’ right to revolution. In other words, “to declare the causes which impel them to the separation.” Congress had to prove the legitimacy of its cause. It had just defied the most powerful nation on Earth. It needed to motivate foreign allies to join the fight.
