What is the sum of in the interior angles of a 21-gon (21 sides)? S=180 (n -2)
The sum of the interior angles of a 21-gon (21 sides) is 3420°.
What are Interior angles?
Any angle that is created between two of a polygon's adjacent sides is said to be its internal angle. The internal angle of a polygon is what we might refer to as the angle measured at the interior portion of a polygon.
The polygon has 21 sides.
we can find the sum of all interior angles of the polygon by using this formula :
S = 180 ( n - 2)
So, S = 180 (21 - 2)
= 180 × 19
= 3420°.

The diagonal PR of a cyclic quadrilateral PQRS bisect ZOPS and ZQRS. Show that PR is a diameter of the circum-circle PQRS.
Let the circum-circle of the cyclic quadrilateral PQRS be O.
The circum-circle of the cyclic quadrilateral PQRSSince PQRS is a cyclic quadrilateral, the four points P, Q, R, S are concyclic. Thus, the line joining any two points among them will pass through the center O of the circum-circle. Since PR bisects ZOPS and ZQRS, it follows that PR passes through the center O of the circum-circle.Therefore, PR is a diameter of the circum-circle PQRS.Let PQRS be a cyclic quadrilateral with PQ bisected at Z, QS bisected at O, RS bisected at P and PS bisected at S. Let PR be the diagonal of the quadrilateral.We have to prove that PR is a diameter of the circumcircle of PQRS.Since the quadrilateral is cyclic, the four angle bisectors all intersect at one point, which is the centre of the circumcircle of the quadrilateral, let us call it O. We know that the angle bisectors divide the angles of the quadrilateral into two equal parts. Therefore, the angles QOP, ROP, POR and QOS are all right angles. This implies that PQRS is a rectangle with the diagonal PR as its diameter.Moreover, the Euler’s theorem states that the sum of the angles of a cyclic quadrilateral is equal to two right angles. This implies that the angles POQ and RQS are equal. So, the line PR bisects the angles POQ and RQS.Thus, we have proved that the diagonal PR of a cyclic quadrilateral PQRS bisects ZOPS and ZQRS, and is a diameter of the circumcircle PQRS.To learn more about the circum-circle of the cyclic quadrilateral PQRS refer to:

A carpenter manufactures chairs and tables. It takes them 3 hours to make a table and 3.5 hours to make a chair. In a month, they do not work for more than 180 hours. On each table, they earn $30, and on each chair, they earn $38. In a month, they want to earn at least $1500. If they manufacture t tables and c chairs in a month, which pair of inequalities represent the correct relationship?
A. 3t+3.5c< 180
30t+38c 1500
B. 3t+3.5c 180
30t+38c≥ 1500
C. 3t+3.5c 180
30t+38c 1500
D. 3t+3.5c 180
30t+38c> 1500
The two expressions that make up an equation or an inequality are connected in a mathematical statement.
How do you identify inequalities?
The equals sign in the equation-like statement 5x 4 > 2x + 3 has been replaced by an arrowhead. This is a prime instance of inequality. This indicates that the left half, 5x 4, is larger than the right part, 2x + 3, in the equation.
A mathematical inequality is a comparison made between two algebraic expressions using the larger than (>), less than (), and other inequality symbols. An inequality pair connected by and or or is referred to as a compound inequality.
B. 3t + 3.5c <= 180 and 30t + 38c >= 1500.
The first inequality represents the constraint that the carpenter cannot work more than 180 hours in a month. The second inequality represents the requirement that they earn at least $1500 in a month.
These two inequalities, combined, describe the conditions that the carpenter must satisfy in order to manufacture tables and chairs in a way that meets both the time constraint and the income requirement.

Is the solution of the equation 2x y 5 and 3x 2y 11 *?.
The value of x = 3 and y = 1 is the solution.
Two or more algebraic equations that have a common variable and are solved simultaneously are referred to as simultaneous equations (that is, simultaneously). For instance, the simultaneous equations x + y = 5 and x - y = 6 are created by concurrently solving two equations that have the same unknown variables, x and y. Multiple techniques, including the substitution method, elimination approach, and visual methods, can be used to solve simultaneous equations.
We have 2 equations,
2x - y = 5 (equation 1)
3x + 2y = 11 (equation 2)
We can solve the given equations simultaneosuly.
Multiplying equation 1 by 2,
4x - 2y = 10
Adding the 2 equations,
4x - 2y = 10
3x + 2y = 11
⇒ 7x = 21
⇒x = 3
Substituting the value of x = 3 in equation 1,
2x - y = 5
⇒ 6 - y = 5
⇒ y = 1
Hence, the values of x and y are 3 and 1 respectively; this is the solution of the equation.

What is the factor of the polynomial a2 2ab b2?.
The factors of polynomial a² - 2ab + b² is equals to the (a - b)², that is (a -b) and (a-b).
To determine the factors we can use the concept of splitting the middle terms and first making the pair of two terms and then finding the common factors from the paired terms and finally the factors for the expression. We have an expression, a² - 2ab + b². Using the concept of to split the middle term. As we see there is three terms in the expression.
Now, multiply the coefficient of first term with the cofficient of last term, i.e., 1 × 1 = 1 Split the middle term cofficient, that is -2 such that sum or difference of spliting terms is -2 and multiplication become 1. Use the basic concept of the product of two negative values results positive value and addition of two negative values provide negative sign, so (-1)(-1) = 1 and -1 + (-1) = -2.Thus, we can rewrite the expression as
=> a² - ab - ab + b²
Make the pair of two terms in the above expression, (a² - ab) - ( ab - b²).
Take common factors from the paired terms,
=> a(a - b) - b(a - b).
Take the common factors in the above equation => (a - b) (a - b)
=> (a - b)¹⁺¹ = (a + b)²
Hence, factor of a² - 2ab + b² is (a-b)² i.e., (a - b) and (a - b).

How much is all 3 angles of a triangle?.
All 3 angles of a triangle always add up to 180 degrees.
This is because a triangle is a three-sided polygon and the sum of the angles in any polygon is always 180 degrees multiplied by the number of sides minus 2. Therefore, in a triangle, which has three sides, the sum of the angles is 180 x (3-2) = 180 degrees. This rule is known as the "triangle angle sum theorem" and is a fundamental property of triangles. It is important to note that this rule applies to all types of triangles, whether they are right triangles, acute triangles, or obtuse triangles. Understanding this theorem is crucial in solving geometric problems related to triangles.

If CAT ~ MUD and the sides of the triangle are the lengths 9 18 21 and 3 6 7 respectively what is the scale factor of triangle CAT to triangle MUD
Answer: The scale factor of triangle CAT to triangle MUD is the ratio of the corresponding side lengths of the two triangles. In this case, we are told that the sides of triangle CAT are 9, 18, and 21 units long, and the sides of triangle MUD are 3, 6, and 7 units long.
To find the scale factor, we divide the length of each side of triangle CAT by the length of the corresponding side of triangle MUD:
Scale factor = (9/3), (18/6), (21/7) =3,3,3
So the scale factor of triangle CAT to triangle MUD is 3. This means that triangle CAT is 3 times larger than triangle MUD.
It's worth noting that the scale factor is the same for all three sides, this means that the two triangles are similar.

The correct way to write greater than 35 is A > 35 where it tells that A having greater value than 35.
In mathematics,
→The greater than symbol (>) is used to indicate that one value is larger than another. For example, if we say "A > B," this means that the value of A is greater than the value of B.
→The less than symbol (<) is the opposite, it indicates that one value is smaller than another. For example, if we say "A < B," this means that the value of A is less than the value of B.
→The greater than or equal to symbol (≥) indicate that one value is larger than or equal to another. For example, if we say "A ≥ B," this means that the value of A is greater than or equal to the value of B.
→The less than or equal to symbol (≤) indicate that one value is smaller than or equal to another. For example, if we say "A ≤ B," this means that the value of A is less than or equal to the value of B.
These symbols are commonly used in mathematical expressions, equations, and inequalities.
To write "greater than 35" in mathematical notation, you would use the greater than symbol (>) followed by the letter 35. For example:
A > 35
This means that A is greater than 35.
Therefore, the correct way to write greater than 35 is A > 35 where it tells that A having greater value than 35.
