La distancia AB es de 30.66m.

<h3>Cómo calcular la distancia AB?</h3>

Para calcular la distancia AB debemos realizar el siguiente procedimiento matemático utilizando el teorema de Pitágoras como se muestra a continuación.

  • a² + b² = c²
  • r² + 17² = 21²
  • r² = 21² – 17²
  • r = 12.33m

De acuerdo a lo anterior, podemos establecer que la base del triángulo de la izquierda mide 12.33m. Ahora debemos calcular la distancia de la base del triángulo de la derecha.

  • a² + b² = c²
  • s² + 17² = 25²
  • s² = 25² – 17²
  • s = 18.33m

De acuerdo a lo anterior, la base del triángulo de la derecha es de 18.33m. Ahora para saber la base total del triángulo que forman ambos cables debemos sumar los valores de la base de los triángulos.

  • 12.33m + 18.33m = 30.66m

Answer:

<em>Karim will never have triple age as his brother, it has happened already 1 year ago, thus he won't give him a gift</em>

Step-by-step explanation:

<u>Equations</u>

Let's make:

x = the number of years from now

Karim now is 22 and Ziad is 8. x years from now Karim will be

22 + x years old and Ziad will be

8 + x years old.

Karim will give Ziad a wonderful gift when:

22 + x = 3(8 + x)

22 + x = 24 + 3x

Solving:

x = -1

This means that Karim will never have triple age as his brother, it has happened already 1 year ago, thus he won't give him a gift

Note: Figure is not drawn to scale. If m1 + m2 = 134°, what is m3? A. 138° B. 49° C. 46° D. 136°
NemiM [27]

Answer:

Measure of angle 3: C (46 degrees)

Step-by-step explanation:

As there is no attachment, I will assume the question is in reference to a triangle. Knowing that a triangle contains 3 angles the answer can be retrieved through simple steps:

m∠1 + m∠2 + m∠3 = 180 degrees, by Sum of Angles in Triangle Theorem, <em>thus;</em>

Through substitution + algebra:

134 + m∠3 = 180,

m∠3 = 46 degrees

The perimeter of a rectangle is 62 m. The length is four more than two times the width. What is the length?
Travka [436]
--------------------------------------------------
Define length and width
--------------------------------------------------
Let x be the width
width = x
Length = 2x + 4

--------------------------------------------------
Formula
--------------------------------------------------
Perimeter = 2(length + width)

--------------------------------------------------
Find Length and width
--------------------------------------------------
62 = 2(2x + 4 + x)
62 = 2(3x + 4)            <em> ← combine like terms  </em> 
62 = 6x + 8                 <em>← remove bracket </em>  
62 - 8 = 6x                  <em>← minus 8 on both sides </em>
6x = 54                      <em> ← swap sides  </em>
x = 54 ÷ 6                   <em>← divide by 6 on both sides</em>
<em>x = 9 m</em>

--------------------------------------------------
Find Length and Width
--------------------------------------------------
Width = x = 9 m
Length = 2x + 4 = 2(9) + 4 = 22 m

--------------------------------------------------
Answer: Length = 22m
