Answer:

(6.08,170.54)

Explanation:

It goes 6 to the left and 1 up

Using Pythagorean theorem= 1/6=tan(angle)

Inverse tan 1/6= angle

= 9.46 degrees

180-9.46= 170.54 degrees is the angle

1^2+(-6)^2=h^2

1+36=h^2

h= square root of 37

h= 6.08

The edge of a cube measures 3.5 x 10 ^ -2 meters. What is the volume of the cube in cubic meters? WRITE Your ANSWERS IN SCIENTIF

Crank

The volume of given cube is: $4.29 * 10^{-5}$ cubic meters

Step-by-step explanation:

Volume of a cube is given by:

$V = a^3$

Given

Edge of the cube = $3.5*10^{-2}$

Putting the value of edge

$V = (3.5*10^{-2})^3\\V = 42.875 * (10^{-2})^3\\V = 42.9 * 10 ^{-2*3}\\V = 42.9 * 10^{-6}\\V = 4.29 * 10 * 10 ^{-6}\\V = 4.29 * 10^{-5}\ cubic\ meters$

The volume of given cube is: $4.29 * 10^{-5}$ cubic meters

The area of a playing card is 48 square centimeters. It is 8 centimeters tall. How wide is it?

il63 [147K]

Answer:6

Step-by-step explanation:

Area of a rectangle = length × width

Length = 8

Breadth = ?

Area = 48

L × B = Area

8 × B = 48

Divide both sides by 8

B = 48 ÷ 8

B = 6

Answer:

El agente debe disparar a un ángulo aproximado de 87.7° con respecto a la horizontal.

Step-by-step explanation:

Sea E la localización del extraterrestre, O, el del hombre de negro, y B, el de la base del edificio. A partir de la información disponible, construimos el diagrama geométrico que indica la presencia de un triángulo rectángulo, el cual puede consultarse en la imagen adjunta.

Podemos determinar el ángulo de disparo mediante la siguiente relación trigonométrica inversa:

$A = \tan^{-1} \frac{443\,m}{18\,m}$
