Answer:
x ≈ 6.5
Step-by-step explanation:
We have the epresion
and we want to find the value of
.
Let's do it step-by-step
Step 1. Multiply both sides of the equation by 20
![tan(18)=\frac{x}{20}](https://tex.z-dn.net/?f=tan%2818%29%3D%5Cfrac%7Bx%7D%7B20%7D)
![20tan(18)=(\frac{x}{20} )(20)](https://tex.z-dn.net/?f=20tan%2818%29%3D%28%5Cfrac%7Bx%7D%7B20%7D%20%29%2820%29)
![20tan(18)=x](https://tex.z-dn.net/?f=20tan%2818%29%3Dx)
Step 2. use the reflexive property of equality: if
then ![b=a](https://tex.z-dn.net/?f=b%3Da)
![20tan(18)=x](https://tex.z-dn.net/?f=20tan%2818%29%3Dx)
![x=20tan(18)](https://tex.z-dn.net/?f=x%3D20tan%2818%29)
Step 3. Using a calculator we get that
. Replacing that value we get
![x=20(0.325)](https://tex.z-dn.net/?f=x%3D20%280.325%29)
x ≈ 6.5
We can conclude that the value of x is approximately 6.5
Answer:
7854 square centimeters
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
A = pi ( 50)^2
A = 2500 pi
Let pi be approximated by 3.14
A = 2500 * 3.14
A =7850 cm^2

Answer:
$6.16
Step-by-step explanation:
1 3/4 Caramels cost is $16.24
1 3/4 Chocolate cost is $22.40.
22.40 - 16.24 = $6.16
<em>$6.16 more</em>
