Mathematics

Answer:

cos 0=90 degrees

Step-by-step explanation:

If sin of 90 is 1 then cos 90 is 0. Since sin and cos are like complementary angles they angles add up to 90 degrees.

\sin(90)  =  \cos(0)

and since sin 90 equal 1 cos of 0 equal 1.

What if we switch angles

Well they are still equal

\sin(0)  =  \cos(90)

But this time sin of 0 is 0 and cos 90 is 0.

El agua de una psicina alcanza 250 cm de altura. Si la estatura de pablo es 1520 mm dentro de la piscina sin que el agua lo cubr
Andrews [41]

Respuesta:

Pablo se cubrirá de agua si se para en la piscina

Explicación paso a paso:

El nivel del agua en la piscina = 250cm.

Altura de Pablo = 1520 mm

Para saber si pablo podría pararse en la piscina sin estar cubierto de agua, necesitamos determinar la altura de Pablo en centímetros.

Convertir la altura de Pablo de milímetro a centímetro;

1 mm hasta 0,1 cm

1520 mm = (1520 * 0,1) = 152 cm

Por lo tanto, pablo mide 152 cm.

Esto significa que la altura del agua en la piscina es mayor que la altura de Pablo y esto lo cubrirá el agua si se para en la piscina.

Here are the areas of the 12 rectangular surfaces that make up the surface area of the podium:

7.5 x 1.5 = 11.25 square feet (Bottom)

1.5 x 1.5 x 2 = 4.5 square feet (Right/Left Bottom Sides)

2.5 x 1.5 x 2 = 7.5 square feet (Right/Left Flat)

1.5 x 1.5 x 2 = 4.5 square feet (Right/Left Top Sides)

2.5 x 1.5 x 2 = 7.5 square feet (Top Front/Back)

2.5 x 1.5 = 3.75 square feet (Top)

7.5 x 1.5 x 2 = 22.5 (Bottom Front and Back)

The area of all these surfaces is 61.5 square feet.
