Answer:

RSTV is a quadrilateral

Interior angles of a quadrilateral sum to 180

<u>Sum of given angles:</u>

  • 2n + 6n + 2n + 5n = 180°
  • 15n = 180°
  • n = 12°

<u>The angles are:</u>

  • 2*12°= 24°, 6*12° = 72°, 2*12° = 24°, 5*12° = 60°

(3)

<u>Sum of angles of a regular 18-gon:</u>

  • S = 180°(18 - 2) = 2880°

<u>Each interior angle is:</u>

  • 2880°/18 = 160°

(4)

<u>Sum of interior angles of a convex heptagon (7-sided polygon):</u>

  • S = 180°(7 - 2) = 900°

(5)

Sum of exterior angles of any polygon is 360°

<u>Each exterior angle of a regular nonagon (9-sided polygon) is:</u>

  • 360°/9 = 40°

a. f(a) =5a+12

we have 1. a=6

Therefore, where ever we find a we'll substitute in 6

f(6) =5(6) +12

6f=30+12

6f=42

so therefore 1. a=6 will match c on the right

2. a=2

f(2) =5(2) +12

2f = 10+12

2f = 22

therefore 2. a=2 will match a on the right

3. a=4

f(4) =5(4) +12

4f=20+12

4f=32

therefore 3. a=4 will match d on the right

4. a=5

f(5) =5(5) +12

5f=25+12

5f=37

therefore 4. a=5 will match b on the right

mr_godi [17]

Answer:

  see below

Step-by-step explanation:

In decimal, the values of the fractions are ...

  -0.2 = -0.200

  -3/7 = -0.429

  -2/8 = -0.250

So, in a, b, c order, they are ...

  a = -3/7

  b = -2/8

  c = -0.2

Descubriendo los triples pitagóricos – Explicado

El Teorema de Pitágoras es ciertamente uno de los teoremas más famosos en todas las matemáticas. Tanto los matemáticos como los laicos lo han estudiado durante siglos, y la gente lo ha demostrado de muchas maneras diferentes. (Incluso al presidente James Garfield se le atribuyó una prueba nueva y original.) Así que sin más preámbulos, aquí está:

El Teorema de Pitágoras: La suma de los cuadrados de las piernas (los dos lados más cortos) de un triángulo recto es igual al cuadrado de la hipotenusa (el lado más largo).

Si usted escoge cualquier número antiguo para dos de los lados de un triángulo rectángulo, el tercer lado usualmente termina siendo irracional – usted sabe, la raíz cuadrada de algo. Por ejemplo, si las patas son 5 y 8, la hipotenusa termina siendo la raíz cuadrada de 89, o aproximadamente 9.43398 ….. (el decimal continúa para siempre sin repetirse). Y si escoges números enteros para la hipotenusa y una de las patas, la otra pata suele terminar siendo la raíz cuadrada de algo.
