Si un triángulo tiene una hipotenusa de 15 cm y un cateto que mide 12 cm, ¿cual es la longitud del otro cateto?
BartSMP [9]

Answer:

   

9cm

Explicación:

El teorema de pitagoras nos dice que la hipotenusa al cuadrado es igual a la suma de los catetos al cuadrado:

c^{2} =a^{2} + b^{2}

Donde c es la hipotenusa y a  y b son los catetos.

Por lo cual, podemos reemplazar c por 15cm y a por 12cm :

15^{2} =12^{2} +b^{2}

Finalmente , debemos resolver la ecuación para b, así que b es igual a :

225=144+b^{2} \\225-144=144+b^{2} -144\\81=b^{2} \\\sqrt{81} =b\\9=b

Por lo tanto, la longitud del otro cateto es 9 cm

The perimeter of a rectangle is 61 feet. The length is 5 more than twice the width. What is the length and width?
DochEvi [55]

Answer:

Length = 22 feet Width= 8.5 feet

Step-by-step explanation:

Perimeter= 61

Let Width= x

Length= 2x+5

Perimeter= 2l + 2w

61= 2(2x+5) + 2x

61 = 2(2x+5+x)

61/2 = 3x+5

30.5 -5 = 3x

25.5 = 3x

25.5/3 =x

x= 8.5

Hence, width = 8.5 feet

Then, the length = 2x+5 = 2(8.5) +5 = 22 feet

Hope this helps!
