Answer:

x = 71.

Step-by-step explanation:

Given  : sin x = cos 19°, where 0°< x < 90°.

To find : For what value of x .

Solution : We have given

sin x = cos 19°.

By the trigonometric rule sin x = cos ( 90 -x ).

We can write cos ( 90 -x ) in place of sin x.

cos ( 90 -x ) = cos 19°.

Then

90 - x = 19 .

On subtracting both sides by 90

-x = 19 -90 .

- x = -71.

On dividing by -1

x = 71.

Therefore, x = 71.

Si consideras como base uno de los rectángulos de dimensiones de 5cm y 3cm ¿cuanto mide la altura de ese prisma?
Vinvika [58]

Respuesta:

h = V / 15

Explicación paso a paso:

El volumen de un prisma rectangular se calcula usando la relación:

Largo ancho alto

Donde, largo y ancho son la dimensión de la base

Por eso,

Volumen = Base * altura

Volumen = (5 cm * 3 cm) * altura

De la pregunta, no se da el volumen, por lo tanto, tomamos el volumen como V en otro para calcular la altura, h

V = 15h

Divide ambos lados entre 15

V / 15 = 15h / 15

V / 15 = h
