How many sides does a convex polygon have if the sum of measures of its angles is 2 520deg?
Answer:
16 sides
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here sum = 2520° , then
180° (n - 2) = 2520° ( divide both sides by 180° )
n - 2 = 14 ( add 2 to both sides )
n = 16
the polygon has 16 sides

Solution:
In the table, we can see that as each round pass, the number of games is being halved.
This means that:
⇒ Round 4 = (Round 3)/2 = 16/2 = 8 games⇒ Round 5 = (Round 4)/2 = 8/2 = 4 games⇒ Round 6 = (Round 5)/2 = 4/2 = 2 gamesHence, in round six, two games will be played.
Answer:
2
Step-by-step explanation:
In the first round, the 128 teams played 64 games. Then in the second round, the 64 teams left played 32 games. That left 32 teams to play 16 games in the third round.
So it is a simple elimination format with number of games going down by half after each round.
4th round: 8 games
5th round: 4 games
6th round: 2 games

What is the arc length of a semicircle with a radius of 14?
Answer:
Perimeter of the semicircle is the formula r(π+2).
Radius r=14 cm
So, perimeter =14(π+2)... where π= 22/7
=2(22+14)=44+28=72 cm
So , the answer is
72 I guess

Solve for x. Round to the nearest tenth, if necessary.
Answer: 52.2
Step-by-step explanation:
N = 43°
Tan43 = x/56
x = 56 * Tan43
x = 52.22084482 or 52.2
Answer: 52.2
Step-by-step explanation:
You're initially given an angle, the adjacent side, and they want the opposite side. Using SOH-CAH-TOA, you can see that the tangent of the angle will give us the opposite side:
[tex]tan(43)=opposite/adjacent=x/56[/tex]
You must use a calculator to find the tangent of 43 degrees. but you get that:
[tex]0.9=x/56[/tex]
Multiply both sides by 56 to get:

the sum of two natural numbers is 28 the product if these numbers is three times the square of the smaller numbers, Find these numbers
Answer:
21 and 7
Step-by-step explanation:
I sort of just used trial and error, but i started with numbers that had a significant difference, like 20, and 8, or 22 and 6
The natural numbers are 7 and 21 if the sum of two natural numbers is 28 the product of these numbers is three times the square of the smaller numbers.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
The sum of two natural numbers is 28 the product of these numbers is three times the square of the smaller numbers
Let x and y be the numbers and x is the smaller number
x + y = 28
xy = 3x²
Plug y = 28 - x in the second equation:
x(28 - x) = 3x²
3x² -28x + x² = 0
4x² -28x = 0
4x(x - 7) = 0
x = 0 or x = 7
y = 28 or y = 21
The natural numbers are 7 and 21
Thus, the natural numbers are 7 and 21 if the sum of two natural numbers is 28 the product of these numbers is three times the square of the smaller numbers.

Escribe la función que representa cada situación:
Utilizando los graficos, veremos que las dos funciones proporcionales son:
y = 3*xy = (3/2)*x¿Como escribir las funciones proporcionales?
Recordamos que una relación proporcional es de la forma:
y = k*x
Donde k es la constante de proporcionalidad.
Para el primer reto, simplemente debemos encontrar un par de valores (x, y) que pertenezca a la linea. Por ejemplo, podemos usar el par (1, 3).
Reemplazando eso en la relación proporcional, tenemos:
3 = k*1
3/1 = k = 3
Entonces la primera función es:
y = 3*x
Para el segundo reto hacemos lo mismo, primero debemos encontrar un par que pertenezca a la linea. Podemos usar el par (2, 3), reemplazando eso en la relación proporcional obtenemos:
3 = k*2
3/2 = k
Entonces la segunda función sera:
y = (3/2)*x.

The angle formed by a tangent on a circle with a radius is always 90 degrees thus the measure of x for the given circle and tangents is 18.
What is a tangent of a circle?The tangent of a circle is a line that intersects the circle at the periphery of the circle.
If you draw a line that goes through the center to the tangent touching point then it will give you a 90-degree angle.
As per the given circle and two tangents.
Since The angle formed by a tangent on a circle with a radius is always 90°.
Therefore, the sum of the other two angles 3x and 126° will be 180°.
3x + 126 = 180
3x = 54
x = 18
Hence "The angle formed by a tangent on a circle with a radius is always 90 degrees thus the measure of x for the given circle and tangents is 18".
