Question 7: Find the value of x. The numbers below are in degrees.<br> 140<br> S<br> 50<br> 20
Lyrx [107]

Given:

A figure.

To find:

The value of x.

Solution:

Draw two parallel lines as shown in the below figure.

If a transversal line intersect two parallel lines, then alternate interior angles are same.

a=20              (Alternate interior angle)

d=b              (Alternate interior angle)           ...(i)

The value of angle d is

d=50-a

d=50-20

d=30

Using (i), we get

b=30

If a transversal line intersect two parallel lines, then same sides interior angles are supplementary angles.

c+140=180

c=180-140

c=40

Now,

x=b+c

x=30+40

x=70

Therefore, the value of x is 70.

Rocío trabaja en una peluquería, le pagan $50 por corte realizado, adicionalmente recibe $25 al día. Si el día miércoles recibió
skad [1K]

Usando conceptos de funciones lineales, se encuentra que hizo 5 cortes.

----------------

Una funcion lineale tiene el seguiente formato:

y(x) = ax + b

En que:

  • a eres lá inclinacion, o sea, lo que es pago por cada corte.
  • b eres el intercepto, o sea, lo pagamiento fixo por día.

----------------

  • Pagan $50 por corte realizado, o sea, a = 50.
  • $25 fixo al día, o sea, b = 25

Entonces, la funcion de su recibimiento y, como funcion de su numero de cortes x, es da por:

y(x) = 25 + 50x

----------------

  • Recibió $275, o sea, y(x) = 275

Entonces, el numero de cortes es:

y(x) = 25 + 50x

25 + 50x = 275

50x = 250

x = \frac{250}{50}

x = 5

Realizó 5 cortes.

how can you add a figure to a composite figure without increasing its perimeter? Draw a diagram to support your answer
goldfiish [28.3K]
We know perimeter is the amount of units around a figure. If we want to add to a composite figure without increasing the perimeter, we must add to it by using the space on the inside of the figure. For example, if we have a square, we can make it a composite figure by splitting the square with a diagonal line. This adds to the figure without adding to its perimeter.
