Un globo vuela entre dos ciudades A y B, que distan entre sí 1.500 m. Los tripulantes del globo ven la ciudad A con un ángulo de
enot [183]

Answer:

La altura del globo con respecto al suelo es 449,6 metros.

Step-by-step explanation:

La afirmación está incompleta. El enunciado completo es: "Un globo vuela entre dos ciudades A y B, que distan entre sí 1.500 m. Los tripulantes del globo ven la ciudad A con un ángulo de depresión de 27°, mientras que para ver la ciudad B es de 36°. ¿Cuál es la altura aproximada del globo con respecto al suelo?

El diagrama geométrico de la situación se encuentra descrita en el archivo adjunto. La altura aproximada del globo puede obtenerse con ayuda de las funciones trigonométricas, en este caso, se recomienda utilizar la función tangente de los ángulos de depresión:

Ciudad A

\tan 27^{\circ} = \frac{h}{1500\,m-x}

0,510 = \frac{h}{1500\,m-x}

Ciudad B

\tan 36^{\circ} = \frac{h}{x}

0,727 = \frac{h}{x}

Donde h y x son la altura con respecto al suelo y la distancia horizontal con respecto a la ciudad A.

A continuación, se elimina la altura de ambas ecuaciones por igualación y se determina la distancia horizontal del globo con respecto a la ciudad A:

0,727\cdot x = 0,510\cdot (1500\,m-x)

1,237\cdot x = 765\,m

x = 618,432\,m

Finalmente, la altura del globo con respecto al suelo es:

h = 0,727\cdot x

h = 0,727\cdot (618,432\,m)

h = 449,600\,m

La altura del globo con respecto al suelo es 449,6 metros.

6. Consider the inequality 12<-3 (x + 4). Which value of x is part of the solution set of this inequality?
Naily [24]

Answer:

-8

Step-by-step explanation:

12<-3 (x + 4)

1. distribute to the -3 to the x and 4 and should get

<em><u>-3*x = -3x</u></em>

<em><u>-3*4 = -12</u></em>

<u>12< -3x - 12</u>

2. now you get rid of the common factors which is -12 so add 12 to both sides and should get

-12+12=0

12+12=24

<u>24< -3x</u>

3. to get x by itself you will have to get rid of -3, so how to do that is divide -3 to both side and should get

-3x/-3= x

24/-3= -8

<u>-8<x</u>

If the measure of xyz is 73 what is the measure of xy <br> a.146<br> b.73<br> c.36.5<br> d.107
icang [17]
146. They are asking for the angle XY, the blue line.

For instance, imagine it is 90 deg, instead of 73, it would cut the circle in two, and XY would be 180 deg. Imagine it would be 45 degrees, it would leave a quadrant, and that's 90 deg.

So the angle * 2 (they are different angles)

I think 'TheBestBrain' thought they were asking for the supplementary angle, but I think it is the arc length angle (blue line)
