Given:
The figure of an equilateral triangle with side length 14 in.
To find:
The height x of the equilateral triangle.
Solution:
We know that the height of an equilateral triangle is:
[tex]h=\dfrac{\sqrt{3}}{2}a[/tex]
Where, a is the length of side of the equilateral triangle.
It is given that the height of the triangle is [tex]x[/tex].
Putting [tex]a=14,h=x[/tex] in the above formula, we get
[tex]x=\dfrac{\sqrt{3}}{2}(14)[/tex]
[tex]x=\sqrt{3}(7)[/tex]
[tex]x=7\sqrt{3}[/tex]

WHY is the number of roots less than or equal to the degree
Answers
The number of roots of a polynomial is always less than or equal to the degree of the polynomial because the degree of f(x) is the sum of the degrees of the factors
Why is the number of roots less than or equal to the degree?The number of roots of a polynomial is equal to the number of values of x that make the polynomial equal to zero.
The degree of a polynomial is the highest exponent of the variable in the polynomial. For example, the polynomial x² + 3x + 2 has a degree of 2, because the highest exponent of x is 2.
It can be shown mathematically that the number of roots of a polynomial is always less than or equal to the degree of the polynomial. This is known as the Fundamental Theorem of Algebra.
Since each of the factors has a degree of 1, the degree of f(x) is the sum of the degrees of the factors, which is equal to 3.
Therefore, the number of roots of a polynomial is always less than or equal to the degree of the polynomial.

What is the equation of a line having a slope of 5 and whose y-intercept is 8?
Answers
5x-y+8=0 is the equation of a line having a slope of 5 and whose y-intercept is 8.
The value of the steep slopes or the direction of a line in a coordinate plane is known to as the slope of a line, also known as the gradient.
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis. Mostly on y-axis, this value c is referred to as the intercept. Y = mx + c represents the equation of a straight line with gradient m and intercept c on the y-axis.
given information like Slope=m=5 and Y intercept equals c=8,
A line's equation is y=mx+c.
As a result of the information provided, the equation for a line is y=5x+8.
A line must have the equation 5x-y+8=0.

What is the equation of a parallel line?Let the condition of the line be hatchet + by + c = 0. Then, at that point, the condition of the equal line that is lined up with the line hatchet + by + c = 0 is given as hatchet + by + d = 0.
The equation of the line is given below.
y = (1/2)x - 5
The equation of the parallel line to the given line is written as,
y = (1/2)x + d

Answers
The ball is hits the ground after 3.4 seconds it strike s
How to determine how long after the ball is hit does it strike the ground?From the question, we have the following parameters that can be used in our computation:
h(t)=-18t^2+60t+4.
Rewrite as
h(t) = -18t² + 60t + 4
When the ball hits the ground, we have
h(t) = 0
So, the equation becomes
-18t² + 60t + 4 = 0
Divide through by 2
-9t² + 30t + 2 = 0
So, we have
9t² - 30t - 2 = 0

Answers
The equation x² + 3x - 3 = 0 has the sum of its roots as 3. This can be found by using the quadratic formula, which gives us two roots x1 and x2. Their sum is x1 + x2 = 3, which is the sum of the roots of the equation.
The correct answer is B: x² + 3x - 3 = 0
The equation has the form of ax² + bx + c = 0.
a = 1, b = 3, c = -3
The sum of the roots can be found using the quadratic formula:
x = (-b ± √(b² - 4ac))/2a
x = (-3 ± √(9 - 4*1*(-3))/(2*1)
x = (-3 ± √15)/2
x = (-3 ± 3√5)/2
x1 = (3 - 3√5)/2
x2 = (3 + 3√5)/2

Answer:
1. ∠YZX = 37°
2. ∠YXZ = 53°
3. XZ = 30 meters
Step-by-step explanation:
1. To solve for an unknown angle, we need to utilize the inverse of a trigonometric function.
⭐What are the inverses of the trigonometric functions?
[tex]sin^-1 (opposite/hypotenuse)[/tex][tex]cos^-1 (adjacent/hypotenuse)[/tex][tex]tan^-1(opposite/adjacent)[/tex]To know which inverse of the trigonometric functions we use, we have to see the type of side lengths we are given (opposite, adjacent, or hypotenuse)
We are given side length XY, which is opposite of ∠YZX, and we are given side length YZ, which is adjacent to ∠YZX. Therefore, we will use [tex]tan^-1 (opposite/adjacent) =[/tex]
Substitute the values we are given into the function:
[tex]tan^-1 (18/24) =[/tex]
Compute this equation using a scientific calculator. I recommend using the Desmos Scientific Calculator:
[tex]= 37[/tex]
∴ ∠YZX = 37°
2. We already know 2 angles (∠YZX = 37°, and ∠ZYX = 90°) Therefore, to find ∠YXZ, we have to utilize the triangle sum theorem.
⭐ What is the triangle sum theorem?
[tex]angle_1 + angle_2 +angle_3 = 180[/tex]The sum of all angles in a triangle is 180°Substitute the angles we know already (∠YZX and ∠ZYX), and solve for ∠YXZ.
[tex]< YZX + < ZYX + < YXZ = 180[/tex]
[tex]37 + 90 + YXZ = 180[/tex]
[tex]127 + YXZ = 180[/tex]
[tex]< YXZ = 53[/tex]
∴ ∠YXZ = 53°
3. We already know 2 side lengths (ZY = 24 meters, and XY = 18). Therefore, to find XZ, we have to utilize the Pythagoras' theorem.
⭐ What is the Pythagoras' theorem?
[tex](C)^2 = (A)^2 + (B)^2[/tex]C is the hypotenuse of the triangle, A is a leg of the triangle, and B is another leg of the trianglePythagoras' theorem can only be used on right trianglesSubstitute the values of the side lengths into the formula:
[tex](XZ)^2 = (XY)^2 + (ZY)^2[/tex]
[tex](XZ)^2 = 18^2 + 24^2[/tex]
Solve for XZ:
[tex](XZ)^2 = 324 + 576[/tex]
[tex](XZ)^2 = 900[/tex]
[tex]\sqrt{(XZ)^2} = \sqrt{900}[/tex]
[tex]XZ = 30[/tex]
∴ XZ = 30 meters

What is the vertical asymptote of X 4?
Answers
The vertical asymptote of X 4 is x = 4, which means that as x approaches 4, the function approaches infinity.
The vertical asymptote of a function is an x-value at which the function tends to approach infinity. In the case of X 4, the vertical asymptote is x = 4. This means that as x approaches 4, the function X 4 approaches infinity. This can be seen by examining the function. As x approaches 4 from the left, the denominator of X 4 becomes increasingly small while the numerator remains constant. This means that the function's value becomes increasingly large as x approaches 4, eventually resulting in an infinite value. In the same way, as x approaches 4 from the right, the denominator of X 4 becomes increasingly large while the numerator remains constant. This means that the function's value becomes increasingly small, eventually resulting in an infinite value. Thus, the vertical asymptote of X 4 is x = 4.
