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

A homeowner wants to build a circular patio. if the diameter of the patio is 20 feet, what is its area to the nearest whole numb
andreyandreev [35.5K]
We are asked to find the area of patio. It is circular so formula used for area is given by:
A= r^{2}  \pi
Where
r = radius = diameter / 2 = 20 / 2 = 10 feet

A = 10^{2} \pi =100 \pi
When we round this to the nearest whole number:
A =100 \pi = 314.159=314ft^{2}
