Can a regular polygon have an interior angles of 169?
Answers
Answer:
No.
Step-by-step explanation:
If it is a regular polygon then the sum of its exterior angles add up to 360 degrees. The number of sides in such a polygon = 360 / exterior angle.
Here each exterior angle = 180-169 = 11 degrees,
Now 11 is not a factor of 360 and if we try to find the number of sides we don't get a whole number, so the answer is NO.
An interior angle 169° cannot form an regular polygon.
What is a polygon?The polygons are the closed shape that has sides and vertices. A regular polygon has all its interior angles equal to each other. An interior angle of a polygon is an angle formed inside the two adjacent sides of a polygon.
For the given situation,
An interior angle of the polygon = 169
The angle of the sum of all the types of interior angles is always equal to 180 degrees.
⇒ [tex]180-169=11[/tex]
Number of sides can be found by dividing the angle by 360°.
We cannot divide 360 by 11, because 11 is not the factor of 360.
Hence we can conclude that an interior angle 169° cannot form an regular polygon.

What is the measure of angle D
Answers
Answer:
52 degrees
Step-by-step explanation:
A triangle's angles all add up to 180 degrees so we can create this equation:
x + 20 + 3x + 32 = 180
Combine like terms.
x + 3x + 20 + 32 = 180
4x + 52 = 180
Subtract 52 from both sides.
4x = 128
Divide.
128 / 4 = 32
x = 32
Plug in the value of x.
x + 20
32 + 20
52
Angle D is equal to 52 degrees.

Answers
Answer:
1. $21
2. $56
Step-by-step explanation:
1.
100% - 30% = 70%
70% * $30 = 0.7 * $30 = $21
2.
100% - 20% = 80%
80% * $70 = 0.8 * $70 = $56
Step-by-step explanation:
The equation for percentages is (percent over 100) times (x over total)
So for the table the equation is 30/100 * x/30
You cross multiply your total x percent and divide by 100.
So 30 * 30 = 900
900 / 100 = 9
30% of 30 is 9.
Now subtract your answer from the original total (30 - 9 = 21)
So the sale price of the tennis table is $21.
Now repeat for your other equation
Your equation is 20/100 * x/70
So 20 * 70 = 1400
1400 / 100 = 14
20% of 70 is 14.
Now subtract your answer from the original total (70 - 14 = 56)
So the sale price of the easel is $56.

Where the x and y values derive from the points given

Step-by-step explanation:
Let x be the number of students in the school.
12 of the 72 students surveyed said they would attend the school pay so
(12/72)x=(1/6)x gives the predicted number of ticket sales. (Here 12*6=72 so it becomes 1/6)
The table shows 210 students purchased tickets so( 1/6)x=210
x=6*210

A 6 foot wide painting should be center on a 14 foot wide wall. how many feet X should be on each side of the painting
Answers
Answer:
4 feet
Step-by-step explanation:
We start by subtracting the 6 from the 14, to get the leftover space on the wall, 8 feet. We then divide that by two, since if the painting is centered there will be two equally-sized spaces on either side of it. This means that X = 4 feet.
Assume we cut the last piece of the pie into two sections (1 and 2) along ray BD
such that m∠ABD = 2x+3, m∠CBD = 4x+7, and m∠ABC = 40°. Based on this information,
would you ask for section 1 or section 2 (you have to pick one) for dessert? Provide numerical evidence to back up your choice. Explain your reasoning and your methods.
Answers
Answer:
If we want the greatest portion of pie, then you must choose the section with the greatest angle. Therefore, we must choose Section 2. But if we want the smallest portion of pie, then we must choose Section 1.
Step-by-step explanation:
From statement, we know that measure of the angle ABC is equal to the sum of measures of angles ABD (section 1) and DBC (section 2), that is to say:
[tex]m \angle ABC = m\angle ABD + m\angle DBC[/tex] (1)
If we know that [tex]m\angle ABC = 40^{\circ}[/tex], [tex]m\angle ABD = 2\cdot x + 3[/tex] and [tex]m\angle DBC = 4\cdot x + 7[/tex], then the value of [tex]x[/tex] is:
[tex](2\cdot x + 3)+(4\cdot x + 7) = 40^{\circ}[/tex]
[tex]6\cdot x +10^{\circ} = 40^{\circ}[/tex]
[tex]6\cdot x = 30^{\circ}[/tex]
[tex]x = 5[/tex]
Then, we check the angles of each section:
Section 1
[tex]m\angle ABD = 2\cdot x + 3[/tex]
[tex]m\angle ABD = 13^{\circ}[/tex]
Section 2
[tex]m\angle DBC = 4\cdot x + 7[/tex]
[tex]m\angle DBC = 27^{\circ}[/tex]
If we want the greatest portion of pie, then you must choose the section with the greatest angle. Therefore, we must choose Section 2. But if we want the smallest portion of pie, then we must choose Section 1.
