Answer:
20-gon
Step-by-step explanation:
First we start with the formula to find what the sum of angles will be if we know the number of sides.
S=(n-2)*180 where S is the sum of angles and n is the number of sides.
Normally you'd plug in n to find S, but you can do the opposite too.
3240=(n-2)*180
Let me know if you need help working it from here.
Answer:
25 Balls
Step-by-step explanation:
If you need area of the trapezoids:
Area of parallelogram = 10×7 = 70 sq. units
Area of each trapezoid = 1/2 × area of parallelogram = 1/2 × 70 = 35 sq. units
![S\frac{O}{H} C\frac{A}{H} T\frac{O}{A}](https://tex.z-dn.net/?f=S%5Cfrac%7BO%7D%7BH%7D%20C%5Cfrac%7BA%7D%7BH%7D%20T%5Cfrac%7BO%7D%7BA%7D)
![Sin=\frac{Opposite}{Hypotenuse} Cos=\frac{Adjacent}{Hypotenuse} Tan=\frac{Opposite}{Adjacent}](https://tex.z-dn.net/?f=Sin%3D%5Cfrac%7BOpposite%7D%7BHypotenuse%7D%20Cos%3D%5Cfrac%7BAdjacent%7D%7BHypotenuse%7D%20Tan%3D%5Cfrac%7BOpposite%7D%7BAdjacent%7D)
7) You have the opposite. You need the adjacent.
![Tan=\frac{Opposite}{Adjacent}](https://tex.z-dn.net/?f=Tan%3D%5Cfrac%7BOpposite%7D%7BAdjacent%7D)
![Tan57=\frac{12}{x}](https://tex.z-dn.net/?f=Tan57%3D%5Cfrac%7B12%7D%7Bx%7D)
![x=\frac{12}{Tan57}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B12%7D%7BTan57%7D)
x = 7.79289... =
<h2>7.8</h2><h2 />
8) You have the hypotenuse. You need the Opposite.
![Sin=\frac{x}{Hypotenuse}](https://tex.z-dn.net/?f=Sin%3D%5Cfrac%7Bx%7D%7BHypotenuse%7D)
![Sin37=\frac{x}{13}](https://tex.z-dn.net/?f=Sin37%3D%5Cfrac%7Bx%7D%7B13%7D)
x = sin37 × 13
x = 7.8235... =
<h2>7.8</h2><h2 />
9) You have the hypotenuse. You need the opposite.
![Sin=\frac{x}{Hypotenuse}](https://tex.z-dn.net/?f=Sin%3D%5Cfrac%7Bx%7D%7BHypotenuse%7D)
![Sin59=\frac{x}{11}](https://tex.z-dn.net/?f=Sin59%3D%5Cfrac%7Bx%7D%7B11%7D)
x = sin59 × 11
x = 9.4288.... =
<h2>9.4</h2><h2 />
10) You have the hypotenuse. You need the opposite.
![Sin=\frac{x}{Hypotenuse}](https://tex.z-dn.net/?f=Sin%3D%5Cfrac%7Bx%7D%7BHypotenuse%7D)
![Sin53=\frac{x}{11}](https://tex.z-dn.net/?f=Sin53%3D%5Cfrac%7Bx%7D%7B11%7D)
x = sin53 × 11
x = 8.7459.... =
<h2>8.7</h2>
