find the value of x. then find the angle measures of the polygon
50 points brainliest answer
Answer: x = 160
Step-by-step explanation:
540 = 100+(x-25)+(x-15)+(1/2)x+(1/2)x
540= 100-40+3x = 60+3x
480 = 3x
x = 160
Answer:
0.5x + 0.5x + (x-25) + (x-15) + 100 = 540
x + x - 25 + x - 15 + 100 = 540
3x + 60 = 540
3x = 540 - 60
3x = 480
x = 480/3
x = 160

find the area of the regular hexagon PQRSTU of sides 8 cm as shown in the figure
Answer:
Area = 245m^2
Step-by-step explanation:
We can split this figure into 2 parts, a rectangle and a trapezoid.
Rectangle Sides = 10m and 20m
Area = 10m x 20m = 200m
Trapezoid formula = a+b/2(h)
a and b are the 2 bases and h is the height
Using a little deductive reasoning we get the following, 5+10/2(6)
This simplifies to 15/2(6) -->
7.5(6) = 45
Thus, our area is 200 + 45, or 245m^2

The graph is Parabola or Graph of Quadratic Function.
The graph has minimum value, not maximum. So ( A ) is not correct for maximum part.
B is not correct for exponential part.
also C is not correct for discrete part as Quadratic graph is continuous.
So the answer is D.

19. If the triangle below is equilateral, write an
expression using parentheses to show the
perimeter of the triangle. Then, give the
simplified expression.
4x - 3
Answer:
Perimeter of the triangle = (12x - 9)
Step-by-step explanation:
Property of an equilateral triangle:
- All sides are equal in measure.
- All interior angles are equal.
Since, measure of one side of the triangle = (4x - 3)
And perimeter of a polygon = Sum of all sides of the polygon
Therefore, perimeter of the given triangle = (4x - 3) + (4x - 3) + (4x - 3)
= (4x + 4x + 4x) - (3 + 3 + 3)
= (12x - 9)
Perimeter of the triangle = (12x - 9)
What are the three trigonometric ratios?
Answer:
There are three basic trigonometric ratios: sine , cosine , and tangent . Given a right triangle, you can find the sine (or cosine, or tangent) of either of the non- 90° angles. Example: Write expressions for the sine, cosine, and tangent of ∠A .

A parent is using a garden hose to fill up a small inflatable pool for her young child. The pool has a capacity of 90 gallons. She turns the water off after 5 minutes, but leaves the hose in the pool for another 3 minutes before putting it away.
In this situation, the relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function.
In that function, which variable is independent? Which one is dependent?
Type your response in the space below.
Answer:
Independent variable = the time. Dependent variable = amount of water per minute
Step-by-step explanation;
The total amount of water depends on how long the hose is left on.
The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.
Time is the independent variable.
The amount of water per minute is the dependent variable.
Given

The pool has a capacity of 90 gallons.
She turns the water off after 5 minutes but leaves the hose in the pool for another 3 minutes before putting it away.
What is the independent variable?Independent variables are the variables that the experimenter changes to test their dependent variable.
What is the dependent variable?A change in the independent variable directly causes a change in the dependent variable.
1. The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.
2. Time is the independent variable.

Based on the graph, which inequality is correct for a number that is to the left of -4?
a
−7 > −4
b
−6 −4
d
−4 < −9
Answer:
From the graph, it is clear that the left of -4 will always be lesser than the -4.
and -6 is the left of -4. so -6 will be lesser than -4.
so, [tex]-6 < -4[/tex] is the correct option.
Therefore, the option 'd' is the correct answer.
Step-by-step explanation:
Let us analyze all the given inequalities
Given the inequality
[tex]-7\:>-4[/tex]
As -7 can not be greater than -4, so [tex]-7\:>-4[/tex] is false.
Given the inequality
[tex]-8>-4[/tex]
As -8 can not be greater than -4, so [tex]-8>-4[/tex] is false.
Given the inequality
[tex]-4 < -9[/tex]
As -4 can not be lesser than -9, so [tex]-4 < -9[/tex] is false.
Given the inequality
[tex]-6 < -4[/tex]
As -4 is always greater than -6, so [tex]-6 < -4[/tex] will be true.
From the graph, it is clear that the left of -4 will always be lesser than the -4.
and -6 is the left of -4. so -6 will be lesser than -4.
so, [tex]-6 < -4[/tex] is the correct option.
Therefore, the option 'd' is the correct answer.

A gym charges $8.75 for each swimming class and a one-time registration fee of $12.50. A student paid a total of $56.25. How many swim classes did the student take?
Answer:
He took 5 swimming classes.
Step-by-step explanation:
The problem states that the student paid a total of $56.25 for the classes and also the one-time registration fee. To find the number of classes, we should first subtract the one-time registration fee from the total.
$56.25 - $12.50 = $43.75
Now that we know he spent a total of $43.75 on the classes without the registration fee, we can divide that number by the cost of one class ($8.75) to calculate the total number of classes he took.
43.75 / 8.75 = 5
