Sarah has some large, polygon-shaped cardboard cutouts that she needs to sort, because she wants to hang them in her geometry classroom. The first division she needs to make is to divide the regular polygons from the irregular ones. In order to save time measuring all angles and sides of each polygon, and owing to the size and number of sides/angles in each shape, Sarah decides to measure just one angle in each polygon. Consider the following angle measures for polygons A through T, and answer the following questions.
a. If each angle measure represented an exterior measure of its polygon, which of the polygons could be regular? Explain your answers.
b. If each angle measure represented an exterior measure of a regular polygon, name each polygon by using its number of sides. (For any figure with more than 12 sides, just use the number: e.g. 45-gon.)
c. If each angle measure represented an interior measure of its polygon, which of the polygons could be regular? Explain your answers.
d. If each angle measure represented an interior measure of its polygon, which of the polygons do we know are convex? Explain your answers.
Answer:
a. ABCDEFHILO
b. 36- 24- 18- dodeca- nona- octa- hexa- penta- square, triangle
c. HLNOPQ
d. ABCD EFGH IJKL MNOP Q
Step-by-step explanation:
a. The exterior angles of a regular polygon have a measure that is 360° divided by the number of sides. If the angle has an integer value, that value must be a divisor of 360°.
Possible regular polygons are ...

Apply sines rule,[tex] \frac{lm}{sin \: 83} = \frac{14}{sin44} \\ lm = \frac{14 \: sin \: 83}{sin \: 44} \\ lm = 20[/tex]
hope this helps..
Good luck on your assignment..
Answer:
LM =20.00356825
Step-by-step explanation:
We will use the law of sines
sin M sin N
-------- = ------------
LN LM
We can find the measure of N since the sum of the angles of triangles is 180
L+ M+ N =180
53+ 44 + N =180
N =180 - 53-44
N =83
sin 44 sin 83
-------- = ------------
14 LM
Using cross products
LM sin 44 = 14 sin 83
LM = 14 sin 83 / sin 44
LM =20.00356825

Answer:
200,000 x 0.05 = 10,000
200,000 + 10,000 = 210,000
This will be 2015 (210,000)
210,000 x 0.05 = 10,500
210,000 + 10,500 = 220,500
2016
220,500 x 0.05 = 11250
220,500 + 11,250 = 231,750
231,750 should be the value

Which of the following side lengths are the legs? 6, 14, and 12
Answer:
The side lengths that are the legs are 6 and 12 because the hypotenuse is the largest side length of a triangle (since there are three side lengths shown).
Answer:
6 & 12
Step-by-step explanation:
In a right triangle, the greatest side length belongs to hypotenuse, other 2 numbers represent the legs
so as per the given, 14 is hypotenuse ans 6 & 12 are legs

Sue wants to increase 160 by 4%
She writes down
160 x 1.4 = 224
Sue's method is wrong.
a) Instead of multiplying by 1.4, write down
what she should have multiplied by
Bill wants to decrease 160 by 6%
b) Complete the statement below to show how Bill can decrease 160 by 6%
160 × ___ =___
Answer:
see explanation
Step-by-step explanation:
An increase of 4% = 104% = [tex]\frac{104}{100}[/tex] = 1.04
Sue should have multiplied by 1.04
(b)
A decrease of 6% = 94% = [tex]\frac{94}{100}[/tex] = 0.94 , thus
160 × 0.94 = 150.4
Step-by-step explanation:
NOTE: Increasing x by p% means multiplying x by (1+p%).
4% = 4/100 = 0.04then
increase 160 by 4% means multiply 160 by (1+4%)
in other words:
1+0.04 = 1.04
increase 160 by 4% means 160 by 1.04
160×1.04 = 166.4
160×(1 - 6%) = 160×(1 - 0.06) = 160×0.94 = 150.4Two roots of a 3-degree polynomial equation are 5 and -5. Which of the following cannot be the third root of the equation ?
0
-5i
-5
5i
5
Answer:
- 5i and 5i
Step-by-step explanation:
The Fundamental theorem of Algebra states that a polynomial of degree 3 has 3 roots, real and/ or complex.
Complex roots occur in conjugate pairs.
Given 2 real roots x = 5, x = - 5
There cannot be complex roots as they occur in pairs which would result in the polynomial having 4 roots instead of 3.
an ostrich is 255 cm.Suppose that you want to make a scale drawing of an ostrich. The scale is 30:1. What height will you make the ostrich in your drawing
Answer:
The height of the drawing should be: 8.5 cm
Step-by-step explanation:
Use the proportion given by the scale in order to find the height "h" that you need to draw:
[tex]\frac{30}{1} =\frac{255}{h} \\30=\frac{255}{h}\\30\,h=255\\h=\frac{255}{30}\\ h=8.5\,\,cm[/tex]

If x^2 is added to x, the sum is 56. Which of the following could be the value of x?
Answer:
-8, 7
Step-by-step explanation:
Set up an equation.
x² + x = 56
Set the equation equal to zero and factor.
x² + x - 56 = 0
(x + 8)(x - 7) = 0
Solve for x.
x + 8 = 0
x = -8
x - 7 = 0
x = 7
The possible x values are -8 and 7.

Answer ASAP 84.9 66.2 38.2 33.8
Step-by-step explanation:
You need to use trigonometric stuff here. Since you're given the hypotenuse and an angle you can plug that right into an equation.
Recall that sin is opposite over hypotenuse and cos is adjacent over hypotenuse.
[tex]sin(\theta)=\frac{o}{h} \\sin(30)=\frac{x}{14} \\0.5=\frac{x}{14} \\x=7[/tex]
Now that you know the opposite side (DC) you can use tan, too, but I'm going to use cos.
[tex]cos(\theta)=\frac{a}{14} \\cos(30)=\frac{x}{14} \\\frac{\sqrt{3} }{2} =\frac{x}{14} \\x=7\sqrt{3}[/tex]
This is the adjacent side (BC). I put it in its exact value, but in decimal form it's ≈12.124.
Now you can do the perimeter:
[tex]2l+2w\\2(12.124)+2(7)\\24.248+14\\38.25[/tex]
Your answer is the 38.2
If k(x) = 5x-6, which expression is equivalent to (k+k) (4)?
Answer:
5(4) - 6 + 5(4) - 6
Step-by-step explanation:
k(x) = 5x - 6
(k+k)(x) = 5x - 6 + 5x - 6
(k+k)(4) = 5(4) - 6 + 5(4) - 6
=> Option D is correct
Hope this helps!
The expression is equivalent to (k+k) (4) will be 5(4) - 6 + 5(4) - 6. The correct option is B.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The expression will be solved as below:-
k(x) = 5x - 6
(k+k)(x) = 5x - 6 + 5x - 6
(k+k)(4) = 5(4) - 6 + 5(4) - 6
Therefore, the expression is equivalent to (k+k) (4) will be 5(4) - 6 + 5(4) - 6. The correct option is B.
