Step-by-step explanation:
36 is the anwser
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°.

find the vertex and the x-inter of the function given below. y = x^2 + 2x + 6
Answer: Vertex = (-1, 5) x-intercepts = No real solutions
Step-by-step explanation:
Vertex = -2/2= -1
-1^2 + 2(-1) +6
1 -2 +6
-1 +6

5 There are 150 men and 250 women in a crowd.
a What fraction of the crowd are men?
Write your answer in its simplest possible form.
b The ratio of married women to unmarried women is 3 to 2.
How many married women are in the crowd?
C More men arrive. The number of men increases by 20%.
How many men are in the crowd now?
d Some of the women leave.
There are now 60 women in the crowd.
What percentage of the women leave?
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
: 30
no of men =150+20%
=150+30

in . 3.5 in 4 9 in 4 in . The triangular prism above has been created with two equilateral triangles and three congruent rectangles . The height of the triangles is 3.5 inches . Find the surface area of the triangular prism . square inches
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

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.
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}
