<h3>Answer: x = 75</h3>

Explanation:

Angles ABC and EFG are same side exterior angles. Any pair of same side exterior angles always add to 180 if we have a set of parallel lines like this.

(angle ABC) + (angle EFG) = 180

x + 105 = 180

x = 180-105

x = 75

A square piece of fabric is the side length of 3.2 cm find the area of the piece of the fabric
Sauron [17]

The area of square fabric piece is 10.24 cm^2

Step-by-step explanation:

Square is a four-sided shape where all sides are equal. The area of square is calculated by using its side.

Given

Side length of fabric piece = s = 3.2 cm

The area of square is given by:

Area = A = s^2

Putting s= 3.2

Area = (3.2)^2\\= 10.24\ cm^2

Hence,

The area of square fabric piece is 10.24 cm^2

Keywords: Square, area

6. Complete la tabla con el número 4.956: Dígito Valor posicional Notación estándar Notación en potencia De esta forma el número
Rzqust [24]

Answer:

6. Miles  {}     cientos       decenas      unidades

  4   {}              9                5               6

7. Catalina podrá hacer un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹

Step-by-step explanation:

6. Los valores posicionales de dígitos son;

Miles  {}     cientos       decenas      unidades

4   {}              9                5                   6

 

7. El número de cuadrados que tiene Fernando = 12

El número de cuadrados que tiene Catalina = 16

El largo y el ancho de un cuadrado son iguales, por lo tanto tenemos;

largo × ancho = Área del cuadrado

largo = ancho = lado del cuadrado

Lado del cuadrado × Lado del cuadrado = Área del cuadrado

(Lado del cuadrado) ² = Área del cuadrado

Lado del cuadrado = √ (Área del cuadrado)

Para Fernando, Área del cuadrado = 12

Lado del cuadrado para Fernando = √12 = 2 · √3 cartones

Para Catalina, Área del cuadrado = 16

Lado del cuadrado para Catalina = √16 = 4 cartones

Por tanto, Catalina podrá realizar un cuadrado con longitud lateral de 4 cartones

8. 45000000 = 4.5 × 10⁶

0.000000000000056 = 5.6 × 10¹⁴

0.000000000034 = 3.4 × 10¹¹
