Let x be the length of each side of the nonagon. We then split up the nonagon into 9 congruent, isosceles triangles, each with base = x and height = 12. Then the area of each triangle is 1/2 • x • 12 = 6x, so the total area of the nonagon will be 9 • 6x = 54x.
To find x, we can use some facts from geometry and trigonometry.
• In any polygon, the sum of the measures of the exterior angles is 360°. So each of these exterior angles will measure 360°/9 = 40°.
• Exterior angles are supplementary to the interior angles. So each interior angle will measure 180° - 40° = 140°.
• Each of the 9 triangles are isosceles with base angles measuring half the interior angles of the nonagon, 140°/2 = 70°.
• Cut the triangle in half along the labeled inradius of the nonagon, which has length 12. In the resulting right triangle, we have
tan(70°) = 12 / (x/2)
and solving for x gives
tan(70°) = 24/x
x = 24/tan(70°)
x = 24 cot(70°) ≈ 8.7
Then the total area of the nonagon is
54x = 54 • 24 cot(70°) ≈ 471.7

least value is 5, median is 20, q1 is 10, q3 is 30, and the greatest value is 50.
Step-by-step explanation:
the least and greatest value is easy, just find the least and greatest numbers. median is in the very middle, so lay out the numbers least to greatest and find the middle. for q1 and q3, find the middle of the least value to median, and median to greatest value. hope this helps

Do 16/22 and 24/33 have the same value? Explain your answer in complete sentences.
Answers
Answer:
Yes,
Step-by-step explanation:
16/22 = 0.72727272727
24/33 = 0.72727272727
When translated into decimals, they both equal 0.72 reoccurring.
x = 0.72727272727...
10x = 7.2727272...
100x = 72.727272727...
100x - x = 90x = [tex]\frac{72}{90}[/tex] which can be translated/simplified into [tex]\frac{16}{22}[/tex] and [tex]\frac{24}{33}[/tex]

Answers
Answer: 3) volume= 28ft³
Surface area= 64ft
4) Volume= 24mi²
Surface area= 192mi
Step-by-step explanation:
3) Volume= length x width x height
= 7x2x2
= 28ft³
Surface area= [(2x2)x2]+[(7x2)x4]
= 8+56
=64ft
4) Volume= 1/2 x length x base x height (whenever finding the areas of triangular shapes you should multiply it by 1/2)
continuation;
= 1/2 x 8 x 6
= 1/2 x 48
= 24 mi³
Surface area= (1/2 x 8 x 6 x 2)+(6 x 6)+(10 x 6)+(8 x 6)
= 48 + 36 + 60 + 48
= 192 mi

∠BOC = 8x - 67∠BOC = 8(14) - 67∠BOC = 112 - 67∠BOC = 45°Answer:
Alrighty... i am happy that you would like an explanation.. that is truly admirable...
let's begin!!!
Step-by-step explanation:
We need to place everything into an equation to solve for x... after that we can substitute the value for x into the expression for m<BOC to get its value (i hope this isn't confusing... the math is easier though... trust me)
8X -67 +9X -75 = 96 Add 67 and 75 to both sides to isolate x
8X +9X = 238 --> 17X = 238
divide both sides by 17 to get x = 14
then subsitute x = 14 into the expression for m < BOC
you get 8(14)-67 = 45
therefore, the measure of <BOC is 45 degrees

Kai bought 3 1/8 pounds of ground beef, 1 3/4
pounds of sausage, and some ground turkey for a chili cook-off. He bought 6 pounds of meat total. How much ground turkey did he buy?
A. 1 1/2 pounds
B. 1 1/8 pounds
C. 4 1/2 pounds
D. 4 7/8 pounds
Answers
Answer:
B. 1 1/8 pounds
Step-by-step explanation:
What we know:
6 Pounds of meat in total
3 1/8 pounds of ground beef
1 3/4 pounds of sausage
Combining the pounds of ground beef and sausage together:
3 1/8 + 1 3/4 = 4 7/8
In all he has 6 pounds of meat. He we know the combined weight of the ground beef and sausage combined: 4 7/8 pounds. Therefore, the equation is...
6 - 4 7/8 =
The answer is...
B. 1 1/8 pounds
Answer:
B. 1 1/8 pounds.
Step-by-step explanation:
Let the weight of turkey he bought be x pounds.
Then we have the equation:
x + 3 1/8 + 1 3/4 = 6
x = 6 - 3 1/8 - 1/ 3/4
Converting to improper fractions
x = 6 - 25/8 - 7/4
We could use a calculator to do this but it also can be done manually by converting all amounts to fractions with denominator 8:
x = 48/8 - 25/8 - 14/8
= 9/8
= 1 1/8 pounds.

15. Consider any eight points such that no three are collinear.
How many lines are determined?
Answers
28
EXPLANATION
there are 8 points of Vishnu three of them are collinear how many lines to the point determine so basically the question mean firstly understand what collinearity mean it means that the points lie in a line so if there are three point if they are collinear it means that they will and makeup one straight line is that no three of them are collinear which means that only two points are collinear not 2.52 be collinear the call through any two points I will it take any two points makes it take this and their straight line is meant to pass through them a straight line always passes through two points at least so we just have to find the total number of the combination of two points which would be taken out from the
combination of eight lines which are there 8.40 so basically we have to find a 32 bit to means the total combination of the two points which are there from the 8.2 it will be 8 factorial upon to factorial in Two States factorial which would give us 56 / to which will be 28586 / to which comes out to be 28 always remember at a point passes through at least two point 1 arbitrarily any two points and a line in is definitely passing through them this is the concept of line and so see which is the option 28 becomes our answer
