The number of sides of the polygon is equal to the sum of the interior angles divided by the sum of the exterior angles, multiplied by two.

The number of sides of a polygon can be determined by examining the measures of its interior and exterior angles. The sum of the measures of the interior angles of the polygon is twice the sum of the measures of the exterior angles. Therefore, the number of sides of the polygon can be calculated by dividing the sum of the interior angles by the sum of the exterior angles and then multiplying that result by two. This is because the number of interior and exterior angles in a polygon are directly related. The sum of the interior angles is always equal to (n-2) times 180 degrees, where n is the number of sides of the polygon. Likewise, the sum of the exterior angles is always equal to 360 degrees. Therefore, the number of sides of the polygon is equal to (sum of the interior angles divided by the sum of the exterior angles) multiplied by two.

The possible distances from art class to math class range from approximately 161.3 feet to 351.3 feet.

What is Pythagoras Theorem?

Pythagoras' theorem is a fundamental principle in geometry that states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

If Braxton walks directly between his art class and math class, then the distance he covers is the shortest distance between the two classrooms, which is the length of the straight line connecting the two points.

We can use the Pythagorean theorem to find this distance:

d = √(95² + 112²) ≈ 144.3 feet

Therefore, the shortest possible distance between the two classrooms is approximately 144.3 feet.

To find the range of possible distances from art class to math class, we need to consider the distance Braxton covers if he stops at his locker.

We can use the triangle inequality to say that the distance between the two classrooms when Braxton stops at his locker must be greater than or equal to the difference between the distance from art class to the locker and the distance from locker to math class:

d ≥ |95 - 112| = 17 feet

So the distance between the two classrooms when Braxton stops at his locker must be at least 17 feet greater than the shortest distance between the two classrooms.

Therefore, the range of possible distances from art class to math class is:

144.3 + 17 ≤ d ≤ 144.3 + (95 + 112) = 351.3 feet

Hence, the possible distances from art class to math class range from approximately 161.3 feet to 351.3 feet.

Now we have to,

→ Find the required value of x.

We know that,

→ Parallel lines are equal to each other.

Forming the equation,

→ x + 26° = 180°

Then the value of x will be,

The probability of making a basket on the sixth shot is 0.075. The probability that the first and second baskets occur on the fourth and eighth shots is 0.031.

For the first shot to be on the sixth trial, five earlier shots must have failed.

The probability of a missed basket is 1 - 0.45 = 0.55.

The probability of five missed baskets in a row is (0.55)5 = 0.166.

The probability of making a basket on the sixth shot is 0.45.

Hence, the probability of making a basket on the sixth shot is 0.45 * 0.166 = 0.075.
There are a few possible ways to get the first and second baskets to happen on the fourth and eighth shots, respectively.

In the end, either of the following two paths will work:
4 failures, then 2 successes, then 2 failures
3 failures, then 1 success, then 1 failure, then 1 success, then 2 failures
Using the multiplication rule, we get the following probabilities for each course:
P(4 failures, 2 successes, 2 failures) = (0.55)4 * (0.45)2 * (0.55)2

= 0.018
P(3 failures, 1 success, 1 failure, 1 success, 2 failures) = (0.55)3 * (0.45) * (0.55) * (0.45) * (0.55)2

= 0.013
The probabilities of the two possible routes must be summed up to arrive at the answer.
Hence, the probability that the first and second baskets occur on the fourth and eighth shots, respectively, is 0.018 + 0.013 = 0.031.

C. y = 24, ∠7 =  89° and ∠8 = 89°

Angle geometry deals with the study of angles, their measurement, and their properties. An angle is formed when two lines or line segments intersect each other at a point.

A. The relationship between ∠7 and ∠8 is that they are vertically opposites angles. Since vertically opposites angles are equal, we can say  ∠7 = ∠8.

B. Since 5y-29 and 3y+19 are vertically opposites angles, we can say equate the two angles (i.e. 5y-29 = 3y+19) and then solve for y

C. 5y-29 = 3y+19

5y-3y= 19 + 29

2y = 48

y = 48/2

y = 24

Let's find either the value of  5y-29 or 3y+19:

Put y = 24 in 5y-29

5y-29 = 5(24) - 29 = 91°

∠7 + (5y-29) = 180°  (sum of angles on a straight line is 180°)

∠7 +  91° = 180°

∠7 = 180 - 91 = 89°

Answer: "A. 3/8"

Step-by-step explanation:

STEP 1: Determine the probability the spinner lands on a multiple of 3. To do this, write out the numbers on the spinner (1-8), and cross out every non-multiple of three (1, 2, 4, 5, 7, 8), this will leave the numbers 3 and 6 unmarked. This being said, 2/8 (1/4) of the numbers on the spinner are multiples of 3.

STEP 2: Determine the probability the spinner lands in a dark green region. In order to do this, write the numbers on the spinner out (1-8), and circle every number representing a dark green region (1, 3, 5, 7). This should leave four numbers (2, 4, 6, 8) un-circled, meaning 4/8 (1/2) of the numbers represent a dark green region.

STEP 3: Add the two answers together (1/4 + 1/2), and you should get the answer 3/8 (A).

NOTE: When adding fractions, make sure they have the same denominators. For example, in this problem, changing 1/2 to 2/4, and doing 1/4 + 2/4, instead of 1/4 + 1/2.

If the pennants have a base of 2 meters, the area of one of the larger pennants is 4m².

It is determined by multiplying the length of the rectangle by its width. The formula for area of a rectangle is Area = Length × Width (A = L × W).

To calculate this, we can use the formula for area of a rectangle which is length multiplied by width.

In this case, the length and width of the pennant is both 2 meters, so we can calculate the area by multiplying 2m * 2m= 4m².

The sports team asked Katie to make 30 larger pennants, so the total area of all the pennants will be 120m² (4m² * 30).

This means that the total area of the 30 larger pennants is 120m².

Answer:

To find the slope of line AB, we use the slope formula:

slope of AB = (yB - yA) / (xB - xA)

where A = (-10, 8) and B = (2, 3).

slope of AB = (3 - 8) / (2 - (-10)) = -5/12

The slope of a line perpendicular to AB will have a negative reciprocal slope, so its slope will be 12/5.

Using the slope-intercept form of the equation of a line:

y = mx + b

where m is the slope and b is the y-intercept, we can find the equation of the line that passes through point X (-5, 10) and has a slope of 12/5.

10 = (12/5)(-5) + b

10 = -24/5 + b

b = 74/5

Therefore, the equation of the line that is perpendicular to AB and passes through point X is:

y = (12/5)x + 74/5

One possible equation for the function shown in the table is:

y = 10 * (0.5)^x

This equation represents an exponential function with a base of 0.5 (i.e. each value is half of the previous value) and an initial value of 10 (i.e. y = 10 when x = 0).

To verify this equation, we can plug in the x-values from the table and see if we get the corresponding y-values:

- When x = 0: y = 10 * (0.5)^0 = 10 * 1 = 10 (matches the table)

- When x = 1: y = 10 * (0.5)^1 = 10 * 0.5 = 5 (matches the table)

- When x = 2: y = 10 * (0.5)^2 = 10 * 0.25 = 2.5 (matches the table)

- When x = 3: y = 10 * (0.5)^3 = 10 * 0.125 = 1.25 (matches the table)

- When x = 4: y = 10 * (0.5)^4 = 10 * 0.0625 = 0.625 (matches the table)

Therefore, the equation y = 10 * (0.5)^x represents the function shown in the table.

The Law of Cosines is a trigonometric formula that relates the lengths of the sides of a triangle to the cosine of one of its angles. It is also known as the Cosine Rule.

The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite to side c, the following equation holds true:

c^2 = a^2 + b^2 - 2ab cos(C)

The side opposite to the angle is of 241 km, hence the parameters are given as follows:

c = 241, a = 207, b = 233.

Then the angle measure is obtained as follows:

241² = 207² + 233² - 2 x 207 x 233cos(C)

96462cos(C) = 207² + 233² - 241²

96462cos(C) = 39057

cos(C) = 39057/96462

The formula for finding the length of a isosceles triangle side is given by:

Length of side = √x² +  y²

Where x and y are the lengths of the other two sides.

To find the length of the side AB, we need to first calculate x and y. We know that BC = 4x + 4 and CA = 3x + 9.

Therefore, [tex]x = BC - CA = 4x + 4 - 3x - 9 = x + -5[/tex]

And [tex]y = CA - BC = 3x + 9 - 4x - 4 = -x + 5[/tex]

Substituting these values in the formula, we get:

Length of side AB = √((x + -5)² + (-x + 5)²)

= √((x² + 25) + (x² + 25))

= √(2x² + 50)

= √(2(8x + 5)²)

5, 6, 7, 8, 9, 10, 12, 14, 15, 17, 18, 19

The total number of values in the set is 12, so the middle value (or the median) will be the average of the 6th and 7th values:

Median = (9 + 10) / 2 = 9.5

To find the lower quartile (Q1), we take the median of the lower half of the data set, which includes the first six values:

Lower half: 5, 6, 7, 8, 9, 10

Q1 = median of the lower half = (7 + 8) / 2 = 7.5

To find the higher quartile (Q3), we take the median of the upper half of the data set, which includes the last six values:

Upper half: 12, 14, 15, 17, 18, 19

Q3 = median of the upper half = (15 + 17) / 2 = 16

Therefore, the lower quartile is 7.5, the middle quartile is 9.5, and the higher quartile is 16.
