Answer:
22.5°
Step-by-step explanation:
First we need to figure out the size of the interior angles on the inside.
The formula of figuring out the total degrees of all the interior angles of any shape is (n-2)×180°.
N is the number of sides.
If we substitute our number of sides (8) we get this:
(8-2)×180°
6×180° = 1080°
Then we divide 1080 by 8 since this is a regular octagon (all angles are equal in a regular shape).
1080° ÷ 8 = 135°
Focusing on the triangle now, we now know that the angle on the tip of the triangle is 135° as it has not been split by the line.
Using the rule of angles in a triangle add up to 180°. We do this sum:
180° - 135° = 45°
There are 2 angles left in the triangle so we do:
45° ÷ 2 = 22.5°
Therefore the angle of x is 22.5°.

Answer:
33 sq units
Step-by-step explanation:
if you section it off into a rectangle and two triangles, the large rectangle that makes up most of the shape is 6x4 units or 24 sq units. each triangle is 3x3 units, so together they would make one 3x3 square. the 3x3 square would have an area of 9, and the answer is 24+9, or 33 sq units

3. Given the statement "x - 4 is a factor of f(x)= 5x* – 22x - 2x2 – 25x +4". explain how to verify the
statement is accurate.
Answers
Step-by-step explanation:
x - 4 = 0
=> x = 4
f(x)= 5x – 22x - 2x² – 25x +4
By remainder theorem,
f(4)= 5(4) – 22(4) - 2(4)² – 25(4) + 4
= 20 - 88 - 32 - 100 + 4 ≠ 0
Since the remainder is not 0, x - 4 is not a factor.

What is 45 minutes before 7 o'clock
Answers
Answer: Its 6:15
Step-by-step explanation:
Its simple math. 7:00 subtract 45minutes, knowing that 60minutes is an hour and that its the 7 hour from the 6 hour. Gets you 6:15.
Yep.
The 45 minutes before 7 o'clock will be 6.15 AM/PM.
What is the time?the indefinite continued progress of existence and events in the past, present, and future regarded as a whole.
In other words, time is something which measure by motion and it is given by einstein that time depends upon motion.
For example time = distance/velocity so it means time also depends on velocity.
In the given question, we know that in
1 hour = 60 minutes
45 minutes before of 7 o'clock = 60 - 45 = 15 minutes after 6 o'clock hence 6.15 minutes will be correct answer.

Karla is selling tickets for a high school play. Child tickets cost $7 and adult tickets cost $13 she sells 180 tickets and collects $1830 Setup a system of equations using C for number of child tickets and A for number of adult tickets to find the number of each ticket sold
Answers
Answer: The number of child tickets is 85 and the number of adult tickets is 95.
Step-by-step explanation:
Let C = Number of child tickets
A = Number of adult tickets.
As per given, we have
C+A=180 (i)
7C+13A=1830 (ii)
Multiply 7 to both sides of equation (ii), we get
7C+7A=1260 (iii)
Eliminate (iii) from (ii) , we get
[tex]6A=570\\\\\Rightarrow\ A=95[/tex]
Put value of y in (i), we get
C= 85
Hence, the number of child tickets is 85 and the number of adult tickets is 95.

Assume all of the sheet of plywood is to be used.
Front and back = 2 * 2x *h
Top and Bottom = 2 * 2x * x
Left/Right side = 2 * x * h
Total area = 4xh + 4x^2 + 2xh
Total area = 6xh + 4x^2
Total area = 600
6xh + 4x^2 = 600
h = (600 - 4x^2)/6x
h = 100/x - 2/3 x
Volume = x * 2x * h
Volume = 2x^2 * (100/x - 2/3 x)
Volume = 200x - 4/3 x^3
I can do this without calculus (I think), but it is much easier to use it.
dV/dx = 200 - 4x^2
This is a maximum when dV/dx = 0
dV/dx = 200 - 4x^2 = 0
4x^2 = 200
x^2 = 50
x = 5√2

Answer:
Hello there!
Your question asks to find what was the size of the population in 2017
Answer: 6,721
In order to solve this problem, we're going to need to use the given information in the question in order to find the population in 2017.
Key information:
In 2010, population was 6500
In 2014, population increased by 10% from 2010
In 2017, population decreased by 6% from 2014.
With the information above, we can solve the problem.
We're going to start with 6500 as our starting population.
We know that the population increased by 10% in 2014, so we would multiply 6500 by 1.10.

Step-by-step explanation:
The sum of two complementary angles is always [tex]90[/tex]°
[tex]A + B = 90[/tex]
[tex]A = B + 14[/tex]
substitute [tex]A[/tex] for [tex]B = 14[/tex]

LAST question !! need help with number 9 but if u can help me with #8 ur an angel
Answers
Answer:
8) interior angle = 160
9) x = 20
Step-by-step explanation:
8)
18-gon has 18 sides
The formula for sum of interior angles for an 18-gon is:
(18x180)-360 = 2880 degrees
2880 degrees / 18 angles = 160 degrees
9)
exterior angles = 360 degrees
360 = (3x-2)+(x+8)+(4x+9)+(2x-1)+(3x)+(4x+6)
360 = 3x-2+x+8+4x+9+2x-1+3x+4x+6
360 = 17x+20
17x = 340
x = 20 degrees
