Answer:

\frac{4\sqrt{5} }{5}

Step-by-step explanation:

\frac{4\sqrt{6} }{\sqrt{30} } =\frac{\sqrt{30} *4*\sqrt{6} } \sqrt{30} {\sqrt{30} } \\\\

\frac{4\sqrt{6*30} }{30} =\frac{4*\sqrt{180} }{30} =\frac{4*\sqrt{36*5} }{30} = \\\\\frac{4*6\sqrt{5} }{6*5} =\frac{4\sqrt{5} }{5}

Calcular el valor del ángulo que falta de un triangulo rectangulo si uno de sus lados mide 25 grados.
Molodets [167]

Considerando la definición de triángulo rectángulo y sus propiedades, el valor del ángulo que falta de un triángulo rectángulo es 65°.

<h3>Definición de triángulo</h3>

Un triángulo es un polígono conformado por tres lados, así como por tres vértices y tres ángulos interiores.

Una de las propiedades de cualquier triángulo indica que la suma de los ángulos interiores es igual a 180°.

<h3>Definición de triángulo rectángulo</h3>

El triángulo rectángulo es una figura geométrica que se considera como un polígono formado por tres lados que forman un ángulo interior recto (es decir, mide 90°) y dos ángulos interiores agudos.

<h3>Valor del ángulo faltante en este caso</h3>

En este caso, sabes que:

  • Al ser un triángulo rectángulo, un ángulo interior mide 90°.
  • Otro ángulo interior mide 25°.
  • La suma de los ángulos interiores es igual a 180°.

Entonces, el valor del ángulo faltante se puede calcular mediante:

90° + 25° + ángulo faltante= 180°

Resolviendo:

115° + ángulo faltante= 180°

ángulo faltante= 180° - 115°

<u><em>ángulo faltante= 65°</em></u>

Finalmente, el valor del ángulo que falta de un triángulo rectángulo es 65°.

Find the volume of a cone with a base diameter of 9 in and a height of 7 in.
Firdavs [7]

Step-by-step explanation:

Formula:

v = \pi \:r {}^{2} \:h

radius is 4.5 because 9÷2=4.5

so it would be

v = \pi \times \:4.5^{2} \times 7

volume = 445.3 units³
