Find the measure of a central angle of a regular polygon with 10​ sides. Round your answer to the nearest tenth of a degree, if necessary.

Answers

Answer 1

Answer:

Step-by-step explanation:

36 is the anwser

Answer 2

The measure of the central angle of a regular polygon with 10 sides is 36°.

What is Polygon?

Polygon is a two dimensional figure which consists of certain number of line segments to form a closed figure.

Minimum three line segments is needed to form a closed figure, which is the triangle.

Circle is also a closed figure, but is not a polygon because it is note formed by line segments.

Regular polygons are polygons whose all sides are equal.

Sum of all central angles will be a full circle or 360°.

So the measure of central angle of a regular polygon = 360° / N, where N is the total number of sides of the regular polygon.

Here, Number of sides, N = 10

So the central angle = 360° / N

                                  = 360° / 10

                                  = 36°

Hence the central angle of a regular polygon with 10 sides is 36°.

Which interval or union of intervals represents the values for which ​f(x)​ is ≤ 0? Select the correct choice below and fill in the answer boxes to complete your choice.

Answers

Answer:

(-∞, -1]∪{5}

Step-by-step explanation:

We know that:

f(x) ≤ 0 is true if the graph of the function is intersecting the x-axis or below the x-axis.

So we can just look at the graph, we can see that in the interval:

(-∞, -1]   (the value x = -1 is included, that is why we use the symbol ] instead of the parenthesis)

the graph is below or intersecting the x-axis

and this also happens at x = 5 or just denoted as {5}

Then the correct notation is:

(-∞, -1]∪{5}

Answers

Answer:

122 in²

Step-by-step explanation:

Applying,

S.A =  bh+ bl+bl+bl............. Equation 1

Where S.A = Surface area of the prism, b = base of the triangle, h = height of the triangle, l = lenghth of the prism

From the question,

Given: b = 4 in, h = 3.5 in, l = 9 in

Substitute these values into equation 1

S.A = 4×3.5+9×4+9×4+9×4

S.A = 14+108

S.A = 122 in²

Hence the surface area of the prism is 122 in²

A: 150/400 (400 is the total men +women) simplifies to 3/8 which is the answer

Answer:

men=150

women=250

total=400

Step-by-step explanation:

a) fraction of men

men/total=150/400=15/40

men/total =3/8

b)let married be x

so unmarried wil be 250-x

married/unmarried=3/2

x / 250-x =3/2

x =3(250-x)/2

2x =750-3x

5x=750

x=750/5

x =150

married =150

unmarried=250-150=100

c)20% of men will be :20x150

100

no of men =150+20%
