please mark as brainliest

Answer:

See below.

Step-by-step explanation:

We are asked to find the value of x, and what these 2 angles are.

We know that these angles are Vertical Angles.

Vertical Angles are angles that are opposite of each other and are equal. They're equal due to the two straight lines crossing over each other at the same angle.

These angles aren't Adjacent Angles because they aren't next to each other. These angles don't share a common side. (Ray)

Since Vertical Angles are equal:

[tex]75 = 4x - 25[/tex]

Simplify for x:

[tex]100=4x\\25 = x[/tex]

x will equal 25°.

An investment of $1,000 at an annual interest rate of 7.5%, compounded annually, will be worth $1,232.28 after 3 years.

Value is a term used to describe the worth of something, either in terms of money, or in terms of importance or usefulness. Value can be determined in terms of the amount of money something is worth, or the level of importance or usefulness it has to someone. When something has a high value, it means that it is worth a lot of money or has a high level of importance or usefulness.

The value of an investment of $1,000 after 3 years at an annual interest rate of 7.5%, compounded annually, can be calculated using the following formula:

Future Value (FV) = Present Value (PV) × (1 + r)ⁿ

Where PV is the present value of the investment ($1,000 in this case), r is the annual interest rate (7.5%) and n is the number of years (3).

Using this formula, we can calculate the future value of the investment after 3 years as follows:

FV = $1,000 × (1 + 0.075)³

FV = $1,000 × 1.23228

FV = $1,232.28

Therefore, an investment of $1,000 at an annual interest rate of 7.5%, compounded annually, will be worth $1,232.28 after 3 years.

The number of home-runs LA Dodgers hit is  35.

Given,

Total home runs in Major league = 583

Home - runs accounted by LA Dodgers = 6 %

Number of home-runs by LA Dodgers

                = 6% of 583

                = 6/100 * (583)

                = 0.06 * 585

                = 34.98

                = 35 approximately

Hence, the total number of homeruns that did the LA Dodgers hit are 35 approximately.

Rounding to the nearest whole number, the tire makes 214 revolutions while traveling 500 feet.

What is Circumference?

Circumference is a term used in geometry to refer to the distance around the edge of a circle or any circular object. It is the total length of the boundary or perimeter of the circle. The circumference is determined by the diameter or radius of the circle, and it is calculated using the formula:

Circumference = π × diameter

The circumference of the tire is equal to the distance it travels in one revolution. Since the diameter of the tire is 28 inches, its radius is 14 inches. Therefore, the circumference of the tire is:

C = 2πr = 2π(14 inches) = 28π inches

To convert the distance of 500 feet to inches, we multiply by the conversion factor 12 inches/foot:

500 feet × 12 inches/foot = 6000 inches

Now we can find the number of revolutions of the tire:

number of revolutions = distance traveled / circumference of tire

number of revolutions = 6000 inches / 28π inches ≈ 214 revolutions

Therefore, rounding to the nearest whole number, the tire makes 214 revolutions while traveling 500 feet.

Option C multiplies one and demonstrates that the result is one, proving that one has the attribute of multiplicative identity.

Any number multiplied by one is equal to itself, according to the multiplicative identity condition of 1. Hence, the following equation illustrates the multiplicative identity feature of 1.

C) 1/4 x 4 = 1

Adding 1/4 to 4 results in: 1/4 x 4 = (1 x 4) / 4 = 4/4 = 1

This demonstrates that when we multiple any number by 1, the result is always the same. Because they involve multiplying many numbers, not just 1, Options A, B, and D do not demonstrate the multiplicative identity characteristic of 1.

Opposite angles are equal

C or KCG isn121

Straight line angle is 180

YCG + GCK = 180

YCG = 180- 121

Another method

All the four angles at a point is 360

YCH + HCK + KCG +YCG is 360

C is 121

121 + X + 121 + X = 360

Ben is incorrect because, all of Ben's expressions are erroneous since none of them equal the number 108 degrees. The correct equation is (n-2) x 180 / n.

A polygon is a geometric shape with a limited number of sides and two dimensions. The sides or edges of a polygon are formed by joining end-to-end segments of a straight line to form a closed shape. The intersection of two line segments, which results in an angle, is referred to as a vertex or corners.

The formula for calculating an interior angle in a regular polygon with n sides is (n-2) x 180 / n.

An internal angle in a pentagon has a measure of (5-2) x 180 / 5 = 108 degrees.

Given that x = -9 is a root of |(x,3,7)(2,x,2)(7,6,x)| = 0, we can use the determinant of the matrix to find the other roots. The determinant of the matrix is given by:

| (x,3,7)(2,x,2)(7,6,x) | = x(x*x - 2*6) - 3(2*x - 7*2) + 7(2*6 - 7*x)

= x^3 - 12x - 3(2x - 14) + 7(12 - 7x)

= x^3 - 12x - 6x + 42 + 84 - 49x

= x^3 - 67x + 126 = 0

Since x = -9 is a root, we can divide the polynomial by (x + 9) to get:

(x^3 - 67x + 126) / (x + 9) = x^2 - 9x - 14

Now we can use the quadratic formula to find the other two roots:

x = (-(-9) ± √((-9)^2 - 4(1)(-14))) / (2(1))

x = (9 ± √(81 + 56)) / 2

x = (9 ± √137) / 2
