Hi there!
[tex]\large\boxed{\text{ sum = 180(n - 2)}}[/tex]
This is the formula for finding the sum of interior angles for a polygon with a number of sides "n".
We can also prove this from the table:
Triangle ⇒ 3 sides: 180(3 - 2) = 180°
Quadrilateral ⇒ 4 sides: 180(4 - 2) = 360°
Pentagon ⇒ 5 sides: 180(5 - 2) = 540°
...And so forth. We can write this as for any polygon with "n" sides:
180(n - 2) = sum (°)

What is the value of x?
In a 45 · 45 · 90 triangle, the hypotenuse is √2 · legs, because a 45 · 45 · 90 triangle is isosceles, so the legs are the same length. So, we have 3√2 · √2 = 6, so the hypotenuse is 6.
x=6
Given two side lengths of 15 units and 9.5 units, with a nonincluded angle of 75°, can you draw no triangles, only one triangle, or more than one triangle
Answer: More than one
Step-by-step explanation: You can do the two side lengths then add the angle any corner giving you a minimum of 3 triangles.
Find m in the diagram please.
Use csc (90) = 10/m.
So, m = 10/csc(90).
m = 8.93997
Answer:
m = 8
Step-by-step explanation:
Here's your solution
=> in traingle DHF and traingle EGF
we have angle DHF and EGF = 90°
and angle F is common , so both traingle are similar by AA similarity
=> 12/m = 15/10
=> m = 120/15
=> m = 8
hope it helps and your day will be full of happiness
Can someone help find the center and the equation
Answer: (x + 4)^2 + (y - 3)^2 = 50
Step-by-step explanation:
Given: x^2 + y^2 + 8x - 6y - 25 =0, which the general form of the circle.
Solution:
Complete the square formula: (x - h)^2 + (y - k)^2 = r^2
Group similar term together on the left side of the equation and move the constant to right side of the equation ( remember to change the sign of the constant.
x^2 + y^2 + 8x - 6y - 25 =0
x^2 + 8x + y^2 - 6y = 25
Complete the Square: (x^2 + 8x + _____) + (y^2 - 6y + _____) = 25
Take half of the coefficient of the linear term for each variable, square the quotient, and add the answer to both side of the equation.
half of the coefficient of the linear term: ( 8/2)^2 = 16 and (-6/2)^2 = 9
(x^2 + 8x + 16) + (y^2 - 6y + 9) = 25 + 16 + 9
Each quality is a trinomial square and need to be factored
(x + 4)^2 + (y - 3)^2 = 50
A corporate team is hosting a fundraising event. It cost them $145 to book the venue, but they are selling the tickets to the event for $15 per person. How many tickets must they sell in order to raise $500?
Answer:
They must sell 43 tickets to raise $500
Step-by-step explanation:
Cost to book the venue = $145
-145 plus 500 (money they need to raise) = $645
Each ticket costs $15
645/15 = 43 tickets
Tatum walks her dog 2/3 mile every day after school. How many miles does she walk her dog in 5 days
The number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)
How to add two fractions?Let we have to add two fractions as:
[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]
Then we will find Lowest Common Multiple (LCM) of [tex]b_1[/tex] and [tex]b_2[/tex]. That will help to make the denominators same.
Once the denominators become same, the numerators can add up directly, giving us the final result of addition.
For this case, we're given that:
Each day, Tatum walks her dog 2/3 milesFor 5 days, the total distance her dog walked = 2/3 + 2/3 + 2/3 + 2/3 + 2/3
Since denominators are same, thus:
[tex]\dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} + \dfrac{2}{3} = \dfrac{2+2+2+2+2}{3} = \dfrac{10}{3}[/tex]
We could've easily done it as: 2/3 + 2/3 + 2/3 + 2/3 + 2/3 = 5 times 2/3 = [tex]5 \times \dfrac{2}{3} = \dfrac{5 \times 2}{3} = \dfrac{10}{3}[/tex]
Thus, the number of miles that Tatutm walk her dog in 5 days is given by: Option B: 10/3 (in miles)

Circumfrance of a circle, (Show working)
Answer:
25.1cm
Step-by-step explanation:
C=2πr
here radius, r=4 cm and π=3.142
Put values in formula.
C=2(3.142)(4)
C=25.1 cm (Rounded to 1 decimal place)
Answer:
25.1 centimeters
Step-by-step explanation:
Formula to find circumference of a circle is C=2πr
Plug in the given values, 3.142 for π, and 4 for r.
C=2 x 3.142 x 4=25.136 centimeters. Round this to 1 decimal place, so our final answer is 25.1

The area of a square is 128x3y4 cm2. What is the length of one side of the square in simplest form
Answer:
We know that the area of the square of side length L is:
A = L*L = L^2
In this case, we know that the area is:
A = 128*x^3*y^4 cm^2
Then we have:
L^2 = 128*x^3*y^4 cm^2
If we apply the square root to both sides we get:
√(L^2) = √( 128*x^3*y^4 cm^2)
L = √(128)*(√x^3)*(√y^4) cm
Here we can replace:
(√x^3) = x^(3/2)
(√y^4) = y^(4/2) = y^2
Replacing these two, we get:
L = √(128)*x^(3/2)*y^2 cm
This is the simplest form of L.

Each length of the side of square B is twice the length of the side of square A.
John says that this means the area of square B is twice the area of square A.
Is John right?
Justify your answer.
Answer:
yes
Step-by-step explanation:
because the area of square is l² so John is righrt
Answer:
Area of square= ²
Area of square A= ²
Area of square B = ?
let the length of square A = x
Area of square A =x²
then the length of square B = 2x
Area of square B =2x²
x²means area of square A
so Area of square B =2 times area of squarf A
