The second angle would be 140⁰. When two angles are supplementary, they add up to 180⁰.
180⁰-40⁰=140⁰

dos aviones parten de una ciudad con direcciones S32°E y E57°N¿ cuál es el angulo que forma sus direcciones?​
Elan Coil [88]

Answer:

El ángulo formado entre las dos direcciones es aproximadamente 115º.

Step-by-step explanation:

Las direcciones dadas en el enunciado significan lo siguiente:

S32ºE - <em>32º al este del sur.</em>

E57ºN - <em>57º al norte del este.</em>

Vectorialmente hablando, cada dirección es la siguiente:

S32ºE

A(x,y) = (\sin 32^{\circ}, -\cos 32^{\circ})

A(x,y) = (0.530, -0.848)

E57ºN

B(x,y) = (\cos 57^{\circ},\sin 57^{\circ})

B(x,y) = (0.545, 0.839)

El ángulo formado entre los dos vectores unitarios (\theta), medido en grado sexagesimales, puede determinarse mediante la siguiente ecuación vectorial:

\theta = \cos^{-1} \frac{A\,\bullet \,B}{\|A\|\cdot \|B\|}

Donde:

\|A\| - Norma de A(x,y).

\|B\| - Norma de B(x,y).

Si sabemos que A(x,y) = (0.530, -0.848), B(x,y) = (0.545, 0.839), \|A\| = 1 y \|B\| = 1, entonces el ángulo formado entre los dos vectores es:

\theta = \cos^{-1} \frac{(0.530)\cdot (0.545)+(-0.848)\cdot (0.839)}{(1)\cdot (1)}

\theta \approx 115^{\circ}

El ángulo formado entre las dos direcciones es aproximadamente 115º.

The length of a rectangular is 5 centimeters less then it width. The perimeter of the rectangle is 26
Zina [86]

Hi there! :)

<u>Answer:</u>

Length = 4 cm

Width = 9 cm


Step-by-step explanation:

Here's the information we know:

- Perimeter = 26 cm

- Width = x (I just replaced the width by "x" because it's what we are looking for)

- Length = x - 5


Now before we can do anything, you need to know what the formula for the perimeter of a rectangular is:<u> P = (2 × Length) + (2 × Width)</u>

Replace all the information you know in the formula and solve the equation by isolating "x":

P = (2 × Length) + (2 × Width)

26 = ( 2 × (x - 5)) + (<u>2 × x</u>)

Multiply "2" and "x" together → 2 × x = <u>2x</u>

26 = ( <u>2</u>(x - 5)) + 2x

Distribute the "2" to the entire parentheses → 2 × x = <u>2x</u> & 2 × -5 = <u>-10</u>

26 = <u>2x</u> - 10 + <u>2x</u>

Add similar terms together → 2x + 2x = <u>4x</u>

26 = 4x <u>- 10</u>

Add 10 to each side of the equation → 26 + 10 = <u>36</u>

36 = <u>4</u>x

Divide each side of the equation by 4 → 36 ÷ 4 = <u>9</u>

<u>9 = x ⇒ Measure of the width</u>


Since the lenght is 5 centimeter less than the measure of the width, in order to find the measure of the length you'll need to subtract "5" from the measure of the width, which is "9":

9 - 5 = Length rectangle

9 - 5 = <u>4 ⇒ Length rectangle</u>


There you go! I really hope this helped, if there's anything just let me know! :)

A=(s-2)180 solve for s
Snowcat [4.5K]

You said that                         A              = (s-2) 180

Divide each side by  180 :    A/180       = s-2

Add  2  to each side:            A/180 + 2 = s
