Answer:

Both are false

Step-by-step explanation:

B is 3 units below P

After dilation B' will be 5 units below P so cannot be on the same horizontal line.

similarly segment CD is 3 units long,

After dilation segment C'D' will be 5 units long so is not equal to segment CD.

Una torre de 28.2 m de altura esta situada a la orilla de un rio, desde lo alto del edificio el ángulo de depresión a la orilla

Svet_ta [14]

Answer:

El ancho del río es 59.9 metros.

Step-by-step explanation:

El ancho del río lo podemos calcular con la siguiente relación trigonométrica asumiendo que la torre forma un triángulo rectángulo con el río:

$tan(\theta) = \frac{CO}{CA}$

En donde:

CA: es el cateto adyacente = Altura de la torre = 28.2 m

CO: es el cateto opuesto = ancho del río =?

θ: es el ángulo adyacente a CA

Dado que el ángulo de depresión (25.2°) está ubicado fuera de la parte superior de la hipotenusa del triángulo que forma la torre con la orilla opuesta del río, debemos calcular el ángulo interno (θ) como sigue:

$\theta = (90 - 25.2)^{\circ} = 64.8 ^{\circ}$

Ahora, el ancho del río es:

$CO = tan(\alpha)*CA = tan(64.8)*28.2 = 59.9 m$

Por lo tanto, el ancho del río es 59.9 metros.

Espero que te sea de utilidad!
