To get rid of the 3.8, we add it.
1.2w - 3.8 + 3.8 = 12.4 + 3.8
1.2w = 16.2

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

Sveta_85 [38]

Answer:

The Accurate and Correct Answer is 50,000nm Or option A.

Step-by-step explanation:

Given:

The sheet is 0.00005m thick

The conversion factor from meters to nanometers:

$1~ nn = 1 ~x~ 10^{-9} ~m$

The thickness of the sheet of paper in nanometers can be found by multiplying the given measurement in meters with the conversion factor;

$=0.00005 ~m~ x~\frac{1~nm}{1~x~10^{-9~m} }$

Hence, the measurement of the sheet in nm is 50 000nm
