From the figure attached with this answer have octagon ABCDEFGH.
We can make a cut to create a plane section in the following shapes:
1. Rectangle
Here ADEH form a rectangle. To make rectangle we take ADEH
2. Octagon
For getting Octagon just cut ABCDEFGH form octagon
3. Triangle
To get triangle cut opposite diagonals. From the figure we can see AOB,BOC,COD,DOE,EOF,FOG,GOH and HOA are triangles.
4. Trapezoid
To get trapezoid ABCD form trapezoid and EFGH form another trapezoid
Answer: 
Step-by-step explanation:
Given: The diameter of the Ferris wheel= 100 feet
therefore, the radius of the Ferris wheel= 50 feet
Also, the highest point of the wheel is 125 feet.
Since , y axis represents the center of the wheel.
The center of the wheel= (0,125)
The equation of circle with center (h,k) and radius 'r' is given by :

Thus, the equation of the circle with center (0,125) and radius=50 is given by :-

Answer:
the atomic number

the atomic number is the number of protons in the shell
Answer:....
Step-by-step explanation:
first we need to find the base of the triangle, so the total is 20, they also give us 12, so we subtract 20-12=8 now divide. 8/2=4. Now we use the 4 and the 60. We use SOH-CAH-TOA, they give us the base now we need to find AB which is the hypotenuse. So we take out the TOA, and the 4 is the adjacent so we take out the SOH, we have CAH now, so we use cos. Now equation time....
since x is the bottom we switch
, which equals 8. AB=8.
Now to find the perimeter. We still use the 4 to find the hypotenuse so we can find the outside side. For this one they tell us to use 45, so now lets see what method we use. SOH-CAH-TOA. We need the hypotenuse and they give us the adjacent, so we use cos again. Now setting up the equation...
x is at the bottom again to we switch.
which equals to 5.657 or you can round it. Now we add everything.
20+12+5.657+5.657= 45.314 or you can round it to 45.
