Before answering the given question, you should know the difference between polygon and regular polygon.
Polygon :- It is closed figure constitute of straight line having different measurements and also having varies angles. Regular polygon :- It is also a closed figure constitute of straight lines which having equal measuresment and all the angles of the given polygon are equal .There are different types of polygon based on the sides :-
A polygon having 3 sided called triangle ,having 4 sides called quadrilateral ,having 5 sides pentagon and so on. Let's Begin :-I have thought to make a 4 side polygon that is quadrilateral.
Steps of construction :-
Step - 1 :- Draw a 5 cm line AB horizontally Step - 2 :- Then , From a point B, Draw a Vertical line of 5 cm and named it BC Step - 3 :- Then, From a point C, Draw a horizontal line of 5 cm and named it CD Step - 4 :- Now, join the line AD Step - 5 :- Measure all the angles form by the 4 sides of the quadrilateral.Result :- All the angles are equal that is 90° each.
Conclusion :- The above figure is square as it is having equal sides and angles.
Now, we have to find the sum of the angles of the polygon :-Here,
All angles are equal in measure 90°Therefore,
The sum of the angles of the given polygon
[tex]\sf{ = 90{\degree} + 90{\degree} + 90{\degree} + 90{\degree} }[/tex]
[tex]\sf{ = 180{\degree} + 90{\degree} + 90{\degree} }[/tex]
[tex]\sf{ = 270{\degree} + 90{\degree} }[/tex]
[tex]\sf{ = 360{\degree} }[/tex]
Hence, The sum of the angles of the above polygon is 360° .

Answer:
d = 3h - 6
Step-by-step explanation:
Given formula:
[tex]h=\dfrac{d}{3}+2[/tex]
Subtract 2 from both sides:
[tex]\implies h-2=\dfrac{d}{3}+2-2[/tex]
[tex]\implies h-2=\dfrac{d}{3}[/tex]
Multiply both sides by 3:
[tex]\implies (h-2) \times 3=\dfrac{d}{3} \times 3[/tex]
[tex]\implies 3(h-2)=d[/tex]
Apply the distributive law [tex]a(b-c)=ab-ac[/tex]
[tex]\implies 3h-6=d[/tex]
[tex]\implies d=3h-6[/tex]
Answer:
[tex]d=3h-6[/tex]
Step-by-step explanation:
[tex]h=\frac{d}{3}+2[/tex]
[tex]h-2=\frac{d}{3}+2[/tex]

The length of the line segment BC is 15 units
Pythagoras theoremIn order to determine the length of BC, we will use the Pythagoras theorem as shown;
AB² = AC² + BC²
Substitute the given parameters
17² = 8² + BC²
BC² = 289 - 64
BC² = 225
BC=. 15 units
Hence the length of the line segment BC is 15 units

Scott needs to replace a broken window at his house. The window is shaped like a triangle with dimensions shown below if glass costs $18.75 per square foot, how much with the replacement window cost?
Answers
Given the cost of glass per square foot, the cost for the replacement of the triangular shaped window glass is 1826.77$.
What is a Triangle?A triangle is simply a polygon with three vertices, three side and three sides.
An equilateral triangle is of triangle with all its three sides equal in length.
There area of an equilateral triangle is expressed as;
A = (√3/4) × a²
Where a is the length of the sides.
Given the data in the question;
Length of the side of the equilateral triangle a = 15ftCost of glass per square foot C = $18.75 per ft²Cost of window replacement CoW = ?First we determine the area of the window which is in the shape of an equilateral triangle.
A = (√3/4) × a²
A = (√3/4) × (15ft)²
A = (√3/4) × 225ft²
A = 97.4279ft²
Now, cost of window replacement will be the area of the window multiplied by the cost of glass per square foot.
CoW = A × C
CoW = 97.4279ft² × $18.75 per ft²
CoW = 1826.77$
Therefore, given the cost of glass per square foot, the cost for the replacement of the triangular shaped window glass is 1826.77$.

Write the point-slope form of the equation of the line through the points (1,-1) and (5,-2)
Answers
Answer:
y + 1 = -1/4 (x - 1) Answer choice C is correct.
Step-by-step explanation:
Point Slope Formula: y - y1 = m (x-x1)
Your points:
(1,-1) and (5,-2)
You need to find the slope first:
Use the formula: y2 - y1 / x2 - x1
Your y2 is -2
y1 is -1
x2 is 5
x1 is 1
-2 - (-1)/5-1
-2 + 1 /4
-1/4 is your slope and the "m" in the formula.
Now we know our y1 is -1 and x1 is 1 you just need to plug them in
y + 1 = -1/4 (x - 1)
Notice that I didn't write y - (-1) this is because the negatives cancel into positives.
Answer choice C is correct.
Answer:
c. [tex]y+1=-\frac{1}{4} (x-1)[/tex]
Step-by-step explanation:
Hi there!
We are given the points (1, -1) and (5, -2)
We want to find the equation of that line using those points, in point-slope form
Point-slope form is written as [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1, y_1)[/tex] is a point
First, let's find the slope of the line
The formula for the slope (m) calculated from 2 points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We already have everything we need to find the slope, but let's label the values of the points to avoid any confusion when calculating.
[tex]x_1=1\\y_1=-1\\x_2=5\\y_2=-2[/tex]
Now substitute:
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-2--1}{5-1}[/tex]
Subtract
m=[tex]\frac{-2+1}{5-1}[/tex]
m=[tex]\frac{-1}{4}[/tex]
The slope of the line is -1/4
Now substitute this into the formula to find point-slope form (remember that this is [tex]y-y_1=m(x-x_1)[/tex], and that m is the slope value)
Therefore:
[tex]y-y_1=-\frac{1}{4} (x-x_1)[/tex]
Now, let's substitute the values of [tex]x_1[/tex] and [tex]y_1[/tex], which we found earlier (which are 1 and -1 respectively) into the equation
[tex]y--1=-\frac{1}{4} (x-1)[/tex]
Simplify
[tex]y+1=-\frac{1}{4} (x-1)[/tex]
This equation matches option c, which is the answer.
Hope this helps!

the volume of a pyramid whose base is aright triangle is 234 units. If the two legs of the right triangle measures 9 units and 12 units find the height of the pyramid.
Answers
If the volume of this pyramid is 234 units, the height of the pyramid is equal to 13 units.
How to calculate the volume of a pyramid.Mathematically, the volume of a pyramid is given by the formula:
[tex]Volume = \frac{1}{3} \times base\;area \times height[/tex]
For the base area:
The area of a right triangle is given by:
[tex]A=\frac{ab}{2} \\\\A=\frac{9 \times 12}{2} \\\\A=\frac{108}{2}[/tex]
A = 54 square units.
Given the following data:
Volume of a pyramid = 234 units.
Side lengths of right triangle = 9 and 12 units.
Now, we can calculate the height of the pyramid:
[tex]234 = \frac{1}{3} \times 54 \times height\\\\234=18h\\\\h=\frac{234}{18}[/tex]
h = 13 units.

So these two angles are actually the same. Since the lines l and m are parallels and those angles are opposite from each other, they are the same.
This means you can solve for x by saying:
3x-63 = 2x+2
x = 65
#7
Since the l and m are parallels, and the angles are NOT opposite, when you add the two angles together, you should get 180 degrees
So:
(2x + 20) + (6x + 24) = 180
