¿se puede hacer un triangulo con las siguientes medidas:2cm ,3cm ,10cm? ayudenme es para mañana
dezoksy [38]

Não, não podemos fazer um triângulo com os comprimentos dos lados de 2 cm, 3 cm e 10 cm. Isso ocorre porque a soma de 2+3 < 10. (in english: No, we cannot make a triangle with the side lengths of measurement 2 cm, 3 cm, and 10 cm. This is because sum of 2+3 < 10).

<h3>What is triangle inequality theorem?</h3>

Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.

Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,

(a+b) > c\\(b+c) > a\\(c+a) > b

Now, for this case, the sides given are:

  • a =2 cm,
  • b = 3 cm,
  • and c = 10 cm

But we see that:

a+ b = 5 cm which is < c which is of 10 cm.

Thus, these lengths don't satisfy the triangle inequality theorem, and therefore, cannot be sides of any triangle.

Which isn't the least expensive per Oz rounded to the nearest cent 20oz for $1.79 or 2 pounds 2 Oz for $2.59
Mars2501 [29]

This problem calls for calculating the unit cost in each case and then comparing the unit costs.

$1.79

---------- = $0.09/oz

20 oz

Noting that 1 lb = 16 oz,

$2.59

---------- = $0.14

18 oz


$1.79 for 20 oz is definitely the better buy (less expensive) when compared to $2.59 for 18 oz.
