Hi there! The answer is h = 65

To find our answer we plug in our data in the formula:

$4082 = 3.14 \times 10 \times 2 \times h$
$4082 = 20 \times 3.14 \times h$
$4082 = 62.8h$

Divide both sides by 62.8
$h = \frac{4082}{62.8} = 65$

\tan \left(18\right)=\frac{x}{20}

noname [10]

Answer:

x ≈ 6.5

Step-by-step explanation:

We have the epresion $tan(18)=\frac{x}{20}$ and we want to find the value of $x$ .

Let's do it step-by-step

Step 1. Multiply both sides of the equation by 20

$tan(18)=\frac{x}{20}$

$20tan(18)=(\frac{x}{20} )(20)$

$20tan(18)=x$

Step 2. use the reflexive property of equality: if $a=b$ then $b=a$

$20tan(18)=x$

$x=20tan(18)$

Step 3. Using a calculator we get that $tan(18)=0.325$ . Replacing that value we get

$x=20(0.325)$

x ≈ 6.5

We can conclude that the value of x is approximately 6.5

Answer:

C = 5/8 (F - 32)

C × 8 = 5/8 × 8 (F - 32)

8C = 5(F - 32)

$\frac{8C}{5} = \frac{5(F - 32)}{5}$
