The value of angle G for both kites are respectively:

∠G = 110°

∠G = 80°

In a kite, the angles between the two non- congruent sides usually have the same angle size. Thus:

∠E ≅ ∠G

In a quadrilateral, the sum of the inner angles is 360 degrees. Thus:

100 + 40 + ∠E + ∠G = 360

Answer:

x=25.1

Step-by-step explanation:

by using Pythagorean theorem, [tex]a^{2} +b^{2}=c^{2}[/tex] where c is the hypotenuse

[tex]18.15^{2}[/tex]= 329.4225

[tex]17.39^{2}[/tex]= 302.4121

since those two side lengths are the legs, the sum of the numbers is the length of the hypotenuse squared

therefore, 631.8356 (the sum) = [tex]c^{2}[/tex]

by taking the square root of 631.8356, you will get approx 25.1 for the hypotenuse (aka x)

the value of the car decreases by 15 percent each year. This means that the value of the car decreases to 85% of its previous year's value every year.

what do you mean by term  decreases  ?

In this context, "decreases" means that the value of the car is getting smaller over time. The term "decrease" is often used in mathematics to describe a decrease in the numerical value of a quantity. In this case, the value of the car is decreasing by 15% each year, which means that its value is getting smaller by 15% of the previous year's value.

In the given question,

The given function for the value of the car is:

v(t) = P(0.85)ⁿ

Here, P is the initial purchase price of the car, and t is the time in years since the car was purchased.

To find the percent that the value of the car decreases by each year, we need to find the ratio of the decrease in value to the initial value, and express it as a percentage.

Let's consider the value of the car after one year, i.e., when t=1. The value of the car after one year is:

v(1) = P(0.85)¹ = 0.85P

The decrease in value from the initial value P is:

P - v(1) = P - 0.85P = 0.15P

Therefore, the ratio of the decrease in value to the initial value is:

(0.15P/P) = 0.15

To express this ratio as a percentage, we multiply by 100, which gives:

0.15 x 100% = 15%

Therefore, the value of the car decreases by 15% each year. This means that the value of the car decreases to 85% of its previous year's value every year.

The unit for the coefficient k would be dollars per unit of length squared.

To find the units for the coefficient k in the formula C = klw, we need to analyze the units of each variable.

C represents the cost of the home, which is measured in dollars.

l represents the length of the home, which is measured in some units of length, such as feet or meters.

w represents the width of the home, which is also measured in some units of length, such as feet or meters.

Therefore, we can determine the units for k by analyzing how the units for C, l, and w combine in the formula C = klw.

Starting with the left-hand side of the equation, we know that C represents dollars.

On the right-hand side of the equation, we have k times l times w. To determine the units of k, we need to figure out what units would make the entire right-hand side of the equation equal to dollars.

Since we are multiplying three quantities (k, l, and w), the units of k must cancel out the units of length in l and w in order to leave us with units of dollars.

This means that the units of k must be dollars per unit of length squared. We can write this as:

k = $/length^2

So, the units for the coefficient k in the formula C = klw are dollars per unit of length squared.

The exponential function of the form y=ab^x that has the given points is y = (25/7)(7/5)^x

We can use the given points to set up a system of equations and solve for the values of a and b in the exponential function y = ab^x.

Using the point (1,5), we get:

5 = ab^1

Using the point (2,7), we get:

7 = ab^2

Now, we can solve for a and b by dividing the second equation by the first:

7/5 = (ab^2)/(ab^1

Simplifying this expression, we get:

7/5 = b

Substituting this value of b back into one of the original equations, we can solve for a:

5 = a(b^1) = a(b) = a(7/5)

What is Quadratic equation?

A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term.

The first condition for an equation to be a quadratic equation is the coefficient of x2 is a non-zero term(a ≠ 0). For writing a quadratic equation in standard form, the x2 term is written first, followed by the x term, and finally, the constant term is written.

Roots of a Quadratic Equation

The roots of a quadratic equation are the two values of x, which are obtained by solving the quadratic equation. These roots of the quadratic equation are also called the zeros of the equation.

Given:

x² - 36 =0

x² = 36

x= √36

x= ±6

hence, the solution is x= +6, -6.

The quotient and the remainder of the rational function are x + 4 and - 4.

In this problem we find the case of a rational function of the form R(x) = P(x) / Q(x), where P(x) and Q(x) are polynomials for the numerator and the denominator, respectively. The result of the rational function is represented by the following expression:

R(x) = S(x) + D(x) / Q(x)

Where:

If we know that P(x) = 2 · x² + 16 · x + 24 and Q(x) = 2 · x + 4, then the quotient and the remainder are, respectively:

R(x) = (2 · x² + 16 · x + 24) / (2 · x + 4)

R(x) = [2 · (x² + 8 · x + 12)] / [2 · (x + 4)]

R(x) = (x² + 8 · x + 12) / (x + 4)

R(x) = [(x² + 8 · x + 16) - 4] / (x + 4)

R(x) = [(x + 4)² - 4] / (x + 4)

R(x) = (x + 4) - 4 / (x + 4)

As a result, the cruise ship has travelled roughly 443.92 miles of distance from its starting point.

This merely indicates that the cruise ship moved 325 miles east since it cruises 325 miles directly east. We can more clearly grasp what is happening if we draw a vertical line where he stops. I created the diagram I believe best illustrates this.

According to the diagram, we now need to determine h because it is the distance between our starting point and destination.

The supplement is 150 degrees because the outside angle is 30 degrees.

As a result, we can now use the cosine rule to find h.

x²  = 325² + 150² - 2(325)(150)cos(180 - 30)

x²  = 105625 + 22500 - 97500 cos(150)

432 = 2(x)(9) + 2(x)(9) + 2(9)(9)

432 = 18x + 18x + 162

432 - 162 = 36x

270 = 36x

x = 270/36

x = 7.5

Hence, the missing length is 7.5 cm.

The sample proportion ^p of Arizona drivers without insurance is 0.175 or approximately 17.5%.

The example extent ^p (p-cap) is the point gauge of the populace extent p. For this situation, the example extent of Arizona drivers without protection is found by partitioning the quantity of drivers without protection (35) by the example size (200).

^p = 35/200 = 0.175

This implies that roughly 17.5% of the inspected Arizona drivers don't have protection. We can utilize this gauge to make derivations about the populace boundary p with a degree of certainty, utilizing factual techniques, for example, certainty spans or speculation testing.

In any case, it is essential to remember that this gauge has a room for mistakes, and the genuine populace extent p might be somewhat unique in relation to the example extent ^p.
