A radio transmission tower is 150 feet tall. How long should a guy wire be if it is to be attached 5 feet from
the top and is to make an angle of 20° with the ground? Give your answer to the nearest tenth of a foot.
a.159.6 ft
c. 154.3 ft
b. 424.0 ft
d. 438.6 ft

Answers

Answer 1
The correct answer would be the first one
Answer 2

Option b is correct, the length of the guy wire should be 424.0 feet.

Let us denote the length of the guy wire as "x."

We can form a right triangle using the height of the tower, the distance from the top to where the guy wire is attached (5 feet), and the length of the guy wire (x).

In the right triangle, the sine of the angle is defined as the ratio of the opposite side (height of the tower - 5 feet) to the hypotenuse (length of the guy wire).

sin(20°) = (height of the tower - 5 feet) / x

To find x, we can rearrange the equation as follows:

x = (height of the tower - 5 feet) / sin(20°)

Substituting the given values:

x = (150 feet - 5 feet) / sin(20°)

x = 145 feet / 0.3420

x = 424.2 feet

Hence, the length of the guy wire should be approximately 424.0 feet.

1.) Pranav completed 12 laps which is 15% of his daily goal. Using a bar model, what is his daily lap goal?

Answers

Answer:

80laps

Step-by-step explanation:

Step one:

number of completed laps=12

let his daily goal be x

so, we are told that 15% of the daily goal is 12 laps

Step two:

Required, the daily goal in laps

15/100*x= 12

0.15x=12

divide both sides by 0.15

x=12/0.15

x= 80laps

Therefore Pranav's daily goal is 80laps

Heeeeelp ayuda amigos 4. En un famoso juicio por asesinato, cuatro amigos: Arturo (A), Bety (B), Carlos (C) y Dora (D) testifican cada uno bajo juramento. Determina si los testimonios son consistentes: Arturo: Bety o Carlos es culpable, pero yo soy inocente. Bety: Si Dora es culpable, entonces los demás son inocentes. Carlos: Si Bety es culpable entonces yo soy inocente. Dora: Arturo o Bety es inocente. Si la gente inocente dice la verdad y la culpable miente, determina si es posible, quien es culpable y quien inocente:

Answers

Answer:

Bety es culpable y los demas son inocentes

Step-by-step explanation:

Siguiendo dos lineas de argumento diferente, Bety es la culpable. Si seguimos las otras dos opciones, el resultado no sera congruente:

Si Arturo es inocente y dice la verdad, el asesino es Bety o Carlos

Si Bety es culpable y miente, Dora sera inocente

Si Carlos es inocente y dice la verdad, Bety es la asesina

Si Dora es inocente y dice la verdad, Arturo es inocente y Bety culpable

Si Dora es inocente y dice la verdad, entonces Arturo o Bety es inocente.

Si Bety es culpable y miente, entonces Dora es inocente.

Si Carlos es inocente y dice la verdad, Bety es la asesina

Si Arturo es inocente y dice la verdad, Bety es la asesina.

Si Arturo es culpable y miente, Bety y Carlos son inocentes

Si Bety es inocente y dice la verdad, Dora sera culpable (ESTO REPRESENTA UNA FALLA EN EL ARGUMENTO)

Si Carlos es culpable y miente, Bety es inocente y el culpable.

Si Arturo es inocente y dice la verdad, el asesino es Carlos y Bety es inocente.

Si Bety es inocente y dice la verdad, Dora sera culpable (ESTO REPRESENTA UNA FALLA EN EL ARGUMENTO)

Answer:

x = 18

m∠HCB = 36

Step-by-step explanation:

The measure of angle FBC is 8x and the measure of angle HCB is 2x. If you add the measures of both angles it will equal to 180 degrees. This can be represented in an equation:

8x + 2x = 180

10x = 180

Divide both sides of the equation by 10 to isolate the x:

10x/10 = 180/10

x = 18

Now that we know the value of x, we can find the measure of angle HCB:

2x

2(18)

36

The measure of angle HCB is 36.
