This is a triangle whose three angles are in the ratio 1:2:3 and respectively measure 30° ( π/6), 60° ( π/3), and 90° ( π/2) and the sides are in the ratio 1:√3: 2.
These triangles are also known as special right triangles, such as 30-60-90 triangles, and 45°-45°-90° triangles. Among all right triangles, the 45°–45°–90° degree triangle has the smallest ratio of the hypotenuse to the sum of the legs, √2/2 and the greatest ratio of the altitude from the hypotenuse to the sum of the legs, √2/4.
The 30°-60°-90° triangle is the right triangle whose angles are in an arithmetic progression. The proof of this fact is simple and follows the fact that if α, α + δ, α + 2δ are the angles in the progression then the sum of the angles 3α + 3δ = 180°. By dividing by 3, the angle α + δ must be 60°. The right angle is 90°, and the remaining angle is 30°.

What is meant by extraneous solution?An extraneous solution (also known as a spurious solution) is a solution that develops during the problem-solving process but is not a true solution to the issue at hand, such as the answer to an equation. Any variable that you are not researching but that might have an impact on the results of your research study is referred to as an extraneous variable in an experiment. Uncontrolled auxiliary variables can result in conclusions regarding the link between independent and dependent variables that are incorrect. The numbers we obtain when solving equations that aren't actually solutions to the equation are referred to as extraneous solutions. Extraneous variables are anything that could potentially influence the outcomes but is not the independent variable.Therefore the correct option is a) Number of people the stadium can hold

Write an equivalent expression by distributing the "-" sign outside the parentheses:
-(-10p - 0. 7q) – 4. 6
After distribution of the negative sing in the parenthesis, the equivalent expression is 10.7p - 4.6
The expression that is given to us is -(-10p - 0. 7q) – 4. 6.
Now, we know that the meaning of equivalent expression is the it has the same value as that of the original expression.
We have to use the "-" and distribute it over the expression to form an equivalent relation,
So, we know,
-(-10p - 0.7q) – 4.6
Here, p is a constant,
Multiplying the negative sign inside of the bracket,
= (-(-10p)-(-0.7p)-4.6
= 10p + 0.7p - 4.6
= 10.7p - 4.6
So, the equivalent expression is 10.7p - 4.6.

{m} - slope.
{c} - intercept along the y - axis.
Given is the equation of the line as -
y = 14x - 4
The given equation of line is -
y = 14x - 4
Slope of the line perpendicular to the given line is -
m{p} = -1/14

Find the sum of the interior angles 1. interior angle sum =?? degrees
Find the measure of one interior angle. 2. one interior angle: ?? degrees
Answer:
Sum of Interior Angles = 1,440º
Each Interior Angle = 144º
Step-by-step explanation:
Sum of Interior Angles = (n − 2) × 180°
Each Interior Angle (of a Regular Polygon) = (n − 2) × 180° / n
----------------------------
10 sided regular polygon
Sum of Interior Angles = (10 − 2) × 180º
Sum of Interior Angles = 1,440º
Each Interior Angle = (10 − 2) × 180º / 10
Each Interior Angle = 144º
Answer:
Sum of interior angles = 1440°
One of the interior angle = 144°
Step-by-step explanation:
This figure have 10 sides so it's called a Decagon
Sum of all interior angles of Decagon : 180 ( n - 2), where n = number of sides the polygon has.
=> 180 (10 - 2) = 1440
To find one of the interior angle : 1440 / 10 = 144

El área y volumen del prisma cuadrangular mencionado son respectivamente:
Área = [tex]16m^{2}[/tex] Volumen = [tex]96m^{3}[/tex]Step-by-step explanation:
Para solucionar este ejercicio debes recordar que un prisma cuadrangular tiene como base y como superficie cuadrados, por lo tanto, para calcular el área de dicho cuadrado puedes utilizar la siguiente fórmula:
Área de un cuadrado = [tex]arista^{2}[/tex]Ya que el ejercicio nos da el valor de la arista (4 metros), podemos reemplazarla en la ecuación y calcular:
Área de un cuadrado = [tex](4m)^{2}[/tex]Área de un cuadrado = [tex]16m^{2}[/tex]Por último, para calcular el volumen debes multiplicar el área superficial, el área del cuadrado calculado, por la altura del prisma, cuyo valor dentro del enunciado es de 6 metros, de esta forma:
Volumen de un prisma cuadrangular = área superficial * alturaVolumen de un prisma cuadrangular = [tex]16m^{2}[/tex] * [tex]6 m[/tex]Volumen de un prisma cuadrangular = [tex]96m^{3}[/tex]Como puedes ver tras los cálculos, el área superficial del prisma es de [tex]16m^{2}[/tex] y su volumen es [tex]96m^{3}[/tex].
