Answer:

  • 2 different triangles

Step-by-step explanation:

  • <em>During a mathematics activity, teacher Julieta distributed to each of her students 4 straws measuring 2 cm, 3 cm, 7 cm and 8 cm. In this activity, Julieta's students had to build triangles with these straws, without cutting them. </em>
  • <em>How many different triangles could each of Julieta's students form with these straws?</em>

==========================================================

  • <em>Triangle inequality theorem says that no any side of a triangle can be longer or equal to the sum the other two sides</em>

<u>Given measures:</u>

  • 2 cm, 3 cm, 7 cm, 8 cm

<u>We see that:</u>

  • 2+3 < 7 and 2+3 < 8

Therefore we can't make triangles with the sides of 2 cm, 3 cm and 7 cm or 8 cm

<u>Possible solutions are:</u>

  • 2 cm, 7 cm, 8 cm
  • 3 cm, 7 cm, 8 cm

So we can make two different triangles

una escalera de 12ft de longitud esta apoyada contra una pared, de modo que su base se encuentra a 4 ft de la pared a nivel del
Marrrta [24]

Answer:

Step-by-step explanation:

Altura = 11.312 pies

i) La escalera que descansa contra la pared formará un triángulo en ángulo recto.

ii) la escalera formará la hipotenusa del triángulo rectángulo dado por h = 12 pies.

iii) La base está dada por 4 pies.

iv) de la fórmula del triángulo en ángulo recto.

   base  = altura = \sqrt{hipotenusa^{2}\hspace{0.15cm}- \hspace{0.15cm} base^{2} }  = \sqrt{12^{2}\hspace{0.15cm} - \hspace{0.15cm}4^{2}  } = \sqrt{144\hspace{0.15cm} - \hspace{0.15cm}16} = \sqrt{128} = \hspace{0.15cm}8\sqrt{2} = 8\times1.414 = 11.312 pies
