This question is a very hard and difficult one to answer.  The main reason 
<span>is because you said "the right rectangular prism shown" and then you didn't </span>
show it.  So all I can tell you is this:

-- The volume of each small cube is

                   (1/4) x (1/4) x (1/4) = 1/64 cubic inch .

-- The volume of the right rectangular prism that's not shown is

<span>   (length in inches) x (width in inches) x (height in inches) cubic inches. </span>

The number of small cubes needed to fill the invisible right rectangular prism is ...

               (volume of the missing right rectangular prism)
divided by
               (volume of each small cube) .

That's

<span>               (volume of the alleged right rectangular prism) </span>
divided by
               (1/64 cubic inch)
<span>=  </span>(64) times (volume of the rumored right rectangular prism)<span> .</span>

3. Use trigonometric ratios to solve for the variable. Show your work. Round lengths to the nearest tenth and angles to the near
Lynna [10]

Answer:

x = 3.4

Step-by-step explanation:

recall that for a right angle with an internal angle θ,

cos θ = adjacent length / hypotenuse

in our case,

θ = 55 deg

adjacent length = x units

hypotenuse = 6 units

substitute these into the formula above

cos θ = adjacent length / hypotenuse

cos 55 = x / 6    (multiply both sides by 6)

x = 6 cos 55 (use calculator)

x = 3.4415

x = 3.4  (rounded to nearest tenth)
