The angular value of x is 3° as per the given the given information in the question.
What is meant by an angle?An angle in Euclidean geometry is the figure produced by two rays, called the sides of the angle, that have a common termination, called the vertex of the angle. Angles formed by two rays lie in the plane containing the rays. Angles are also generated by the intersection of two planes. These are referred to as dihedral angles. Two intersecting curves can also define an angle, which is the angle of the rays lying tangent to the respective curves at their point of intersection.
Given,
m ∠GQP=80
m ∠RQP=3+59x
m ∠RQG=32x+4
From the figure,
m ∠RQG+ m ∠GQP= m ∠RQP
32x+4+80°=3+59x
27x=81°
x=3°
Therefore, the value of x=3°

The correct option regarding the price is C. no; The packs of socks are marked up to $7 and then discounted to $4.20.
How to calculate the price?In this situation, a shoe store buys packs of socks wholesale for $5 each and marks them up by 40%. The price will be:
= Original price + Markup
= 5 + (40% × 5)
= 5 + 2
= $7
Then, the store decides to discount the packs of socks by 40%. This will give a price of:
= 7 - (40% × 7)
= 7 - 2.8
= $4.2
The price isn't discounted to $5.

the side length of a square is √8 find the area.
is the number rational or irrational?
Answers
The area of a square with a side length √8 represents a rational number, which is equal to 8 square units.
Is the number behind the area of the square a rational number?
Rational numbers are real numbers of the form m / n, where m and n are integers, where n ≠ 0. The rest of real numbers are irrational (i.e. π, √5, ∛7, e) Besides, the area of the square is determined by the following formula:
A = l²
Where l is the side length of the square.
First, substitute the side length of the square in the area formula:
A = (√8)²
Second, use algebraic properties to simplify the expression and find the corresponding result:
A = ([tex]8^{\frac{1}{2} }[/tex])²
A = 8
This number represents a rational number as 8 is equivalent to the rational number 8 / 1.

The solution of the absolute value equation |3x - 6| = 12 is x= 6 and x = -2
The absolute value equation is
|3x - 6| = 12
We can write the absolute value equation in two ways
3x - 6 = 12
-(3x - 6) = 12
We have to solve each equation
The first equation is 3x - 6 = 12
3x - 6 = 12
3x = 12+6
3x = 18
x = 18/3
x = 6
The second equation is -(3x - 6) = 12
Apply the distributive property
-3x + 6 = 12
-3x = 12 - 6
-3x = 6
x = 6/-3
x = -2

Given the: Triangle RST with vertices R(2, 0), S(4, 0), and T(1, -3). And the image of triangle RST after a rotation has vertices R'(0, -2). S'(0, -4), and T(-3, -1)
From the given vertices it is obvious that the relation between preimage and image is defined as

Zeros of a PolynomialZeros of polynomial are the points where the polynomial equals zero on the whole. In simple words, we can say that zeros of polynomial are values of the variable such that the polynomial equals 0 at that point. Zeros of a polynomial are also referred to as the roots of the equation and are often designated as α, β, γ respectively.
The zeros of a polynomial f(x) are the values of x which satisfy the equation f(x) = 0. Here f(x) is a function of x, and the zeros of the polynomial are the values of x for which the f(x) value is equal to zero. The number of zeros of a polynomial depends on the degree of the equation f(x) = 0. All such domain values of the function, for which the range is equal to zero, are called the zeros of the polynomial.
To find the zeros of this polynomial function, we have to write the function appropriately.
x⁴ - 6x³ - 21x² = 150x - 100

The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system
The slope-intercept form of a straight line is:
y = mx + c,
where m is the slope and c is the y-intercept
When the two lines are perpendicular, the product of their slope is -1 i.e.
m₁ x m₂ = -1
where m₁ and m₂ represent the slope of the lines
Let the slope of the given line be m₁ and the slope of the unknown line be m₂
Line1(given):
y = 12x−2 and m₁ x m₂ = 12
m₁ x m₂ = -1

Two plants will never be of the same height.
Given, the height of an experimental plant after x days can be
represented by the formula 3(4x + 2).
The height of a second plant can be represented by the formula 6(2x + 2).
We have to state that will the two plants ever be of the same height,
Let assume that, the height of two plants be same,
So, 3(4x + 2) = 6(2x + 12)
On simplifying, we get
12x + 6 = 12x + 72
On subtracting 12x from both the sides, we get
12x + 6 - 12x = 12x + 72 - 12x
6 ≠ 72
It is an absurd condition, so we do not have any solution for x.
So, the two plants will never be of the same height.
