  • <em>Answer:</em>

<em>h ≈ 0.25 cm</em>

  • <em>Step-by-step explanation:</em>

<em>Hi there !</em>

  • <u><em>density formula</em></u>

<em>d = m/V</em>

<em>V = l×w×h</em>

<em>replace</em>

<em>2.17 = 438/(40×20)×h</em>

<em>2.17 = 438/800×h</em>

<em>2.17×800×h = 438</em>

<em>1736h = 438</em>

<em>h = 438/1736</em>

<em>h ≈ 0,25 cm</em>

<em>Good luck !</em>

The right triangle shown has angles X, Y, and Z and side lengths a, b, and
laiz [17]
So attached is a picture of the triangle you are talking about and listed under are the choices:

A.) Cos Z=b/c 
B.) Sin X=c/b 
C.) Tan X=b/a 
<span>D.) Tan Z=a/b
</span>
The answer would then be B. SinX = c/b.

Just remember SOH CAH TOA:

Sinθ=  Opposite         Cosθ =    Adjacent             Tanθ=   Opposite
         Hypotenuse                   Hypotenuse                        Adjacent

Using the triangle in the scenario, you just need to identify which side is which. 

Given m∠Z
Adjacent = b
Opposite = a
Hypotenuse = c

SinZ=  a         CosZ = b             TanZ= a 
            c                      c                        b

Given m∠X:

Adjacent = b
Opposite = a
Hypotenuse = c

SinX= <u> b </u>        CosX =<span><u> a </u></span>            TanX=<span><u> b </u></span>
            c                      c                        a

So the answer is B. 

Attached is a picture of how I assigned the sides depending on the angle used.

Answer:

Just substitute each number into the expression:

5(5) - 6(3) + 20(1/4)/4(3)(1/4) = 25 - 18 + 5/3 = 7 + 5/3 = 26/3 or 8 and 2/3.
