hoa [83]

Answer:

The answer to your question is AC = 9.9

Step-by-step explanation:

To solve this problem use trigonometric functions. The trigonometric function that relates the hypotenuse and the adjacent side is cosine.

             cos α = \frac{adjacent side}{hypotenuse}

Solve for hypotenuse

              hypotenuse = \frac{adjacent side}{cos\alpha }

Substitution

             hypotenuse = \frac{9}{cos 24}

Simplification and result

             hypotenuse = 9.85

The volume of a cube can be calculated using the formula V = s^3, where s is the side length. What is the volume of a cube with
kumpel [21]

Answer:

Volume of a cube with side length 1/3 of a meter = 1/27m^3

Step-by-step explanation:

Let

1 meter = m

V = s^3

Where,

V= volume of a cube

s= side length

s = 1/3 of a meter

= 1/3 × m

= 1/3m

V = s^3

= 1/3^3

= 1/3m * 1/3m * 1/3m

V = 1/27m^3

Volume of a cube with side length 1/3 of a meter = 1/27m^3
