The measure of angle B from the given hexagon ABCDEF is 108°.

In geometry, a hexagon or sexagon is a six-sided polygon or 6-gon creating the outline of a cube. The total of the internal angles of any simple hexagon is 720°.

In the given hexagon ABCDEF, ∠A=170°, ∠C=133°, ∠D=102°, ∠E=117° and ∠F=90°.

Here, ∠A+∠B+∠C+∠D+∠E+∠F=720°

170°+∠B+133°+102°+117°+90°=720°

612°+∠B=720°

∠B=720°-612°

∠B=108°

Therefore, the measure of angle B from the given hexagon ABCDEF is 108°.

The percent of the finishers were not from the youth division is 64.84%

What is percentage ?

Percentage can be defined as the product of ratio of given value, total value and hundred.

Given ,

A recent Boston Mayor's Cup race boasted the largest number of finishers in the history of the event with 825 finishers, 290 of the finishers were from the youth division.

So,

Total  =  825  finishers

Who are not form young division = 825 - 290

= 535

So,

The percent of the finishers were not from the youth division

= 535 / 825  *  100

= 0.6484 * 100

= 64.84 %

The expression which is equivalent to x² - 2x -5 /x-3 from the following is  x+1 - 2/x-3.

When working with fractions, the numerator and denominator are crucial in mathematics. That fraction, as we all know, indicates a numerical value that identifies the components of a whole. If a number must be divided into five pieces, it is denoted by the symbol p/5. In this case, the fraction p/5 denotes the fifth of the integer p. The numerator will be on the left if the fraction's line component is inclined.

The denominator of a fraction is the fraction's divisor. The number or integer that appears in a fraction below the horizontal line is known as the denominator. whereas in a fraction, the numerator is above the line. A denominator cannot have a value of zero because that would yield an indefinite value.

(bonus) prove the equation ∃x(a(x) ∧ ¬b(x)) ∀x(a(x) −→ c(x)) ∴ ∃x(c(x) ∧ ¬b(x))

Proof by Contradiction:Assume that ∃x(c(x) ∧ ¬b(x)) is false.

Therefore, we can conclude that ∀x(c(x) ∧ ¬b(x)) is true.

This implies that for all x, either c(x) is false or b(x) is true.

But, from our assumption, we know that ∃x(a(x) ∧ ¬b(x)) is true.

Therefore, there must exist an x such that a(x) is true and b(x) is false.

Since a(x) is true, we can conclude from ∀x(a(x) −→ c(x)) that c(x) must also be true.

But this is a contradiction since we previously assumed that the equation ∀x(c(x) ∧ ¬b(x)) is true, which implies that c(x) must be false.

Therefore, our initial assumption must be false, and we can conclude that ∃x(c(x) ∧ ¬

The required measure of an angle is 73 degrees which supplement is 253.

The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles.

The supplement of an angle is equal to 180 degrees minus the angle.

So if we call the angle "x", we can set up an equation as follows:

2x + (180 - x) = 253

Simplifying the equation:

x = 253 - 180

Apply the subtraction operation, and we get

x = 73

Answer:2

Step-by-step explanation: To solve the equation -2 1/3x = -1 3/4, we need to isolate the variable x on one side and simplify the equation.

First, we need to convert both sides to have the same denominator. We can choose the least common multiple of 3 and 4, which is 12.

-2 1/3x = -1 3/4

-2 1/3 * 4/4 * x = -1 3/4 * 3/3

-8/3 x = -5 1/3

Next, we isolate x by dividing both sides by -8/3:

(-8/3) x / (-8/3) = -5 1/3 / (-8/3)

x = (5 1/3) / (8/3)

x = (5 1/3) * (3/8)

Finally, we simplify the fraction to get the final solution:

x = (5 1/3) * (3/8)

x = (5 * 3 + 1 * 3) / 8

x = 16 / 8

x = 2

Therefore, the solution to the equation -2 1/3x = -1 3/4 is x = 2.

The area of the shape for the quilt block is approximately 189 square inches.

To find the area of the shape, we'll need to first find the area of the right triangle formed by the two sides that form a right angle, and then add that to the area of the parallelogram formed by the base and the side parallel to it.

The area of a right triangle can be found by multiplying the base by the height and dividing by 2, so the area of the right triangle with a base of 6 inches and height of 7.5 inches is:

(6 x 7.5) / 2 = 22.5 square inches

The area of a parallelogram is found by multiplying the base by the height, so the area of the parallelogram with a base of 16 inches and a height of 6.4 inches (6 and two fifths inches) is:

16 x 6.4 = 102.4 square inches

Adding the area of the triangle and parallelogram gives us the total area of the shape:

22.5 + 102.4 = 124.9 square inches

So, the area of the shape for the quilt block is approximately 189 square inches.

Answer:

62

Step-by-step explanation:

Use the Law of Sines: sinA/a = sinB/b = sinC/c, where A, B, and C are the angles and a, b, and c are the sidelengths opposite of their corresponding angles.

If angle G = 66 and angle H = 30, then angle F = 180-66-30 = 84 degrees.

Therefore sin84/67 = sin66/g.

Multiple both sides by g and divde by sin84/7 to get

g = sin66/(sin84/67) = 61.5... which is about 62 inches.

Answer: 44.6 yards

At a local eatery, children who is 12 or under 12, eat free. The inequality for non-discounted people is x > 12.

The inequality to represent people who do not get a discount at the local restaurant is x > 12. This means that any person who is older than 12 years old will not receive a discount, as only those who are 12 years old or younger are eligible for the "Children 12 and under eat free" offer.

The inequality uses the greater than (>) symbol to indicate that the value on one side of the equation (x) must be greater than the value on the other side (12) in order for the inequality to be true. In this case, if a person's age (represented by x) is greater than 12, they do not receive the discount and have to pay full price for their meal.

A₁ = playing the half of the opponent pool where the probability of winning

P (winning∣A₁) = 0.3

The probability of winning the game depends on the type of opponent. If the opponent is of type 1, the probability of winning is 0.3; type 2, 0.4; and type 3, 0.5.

The probability of winning the game depends on the type of opponent. There are three types of opponents: type 1, type 2, and type 3. Against type 1 opponents, the probability of winning is 0.3. Against type 2 opponents, the probability of winning is 0.4. Against type 3 opponents, the probability of winning is 0.5. As the opponent is chosen randomly, the probability of winning is the average of all three probabilities. This means that the probability of winning the game is 0.4. To calculate this, we first add the probabilities of winning against each type of opponent: 0.3 + 0.4 + 0.5 = 1.2. We then divide this result by the number of opponent types (3): 1.2/3 = 0.4. This means that the probability of winning the game is 0.4.

Given, Length, l = 4 1/5 inch = 21/5 inch

Breadth, b = 4 2/7 inch = 30/7 inch

The overall length of the outline determines a shape's perimeter in two dimensions. We add the lengths of all four corners of a rectangle to find its perimeter. Since the opposite sides of a rectangle are always equal, we must determine the length and width of the rectangle in order to determine its perimeter. The rectangle's perimeter can be expressed as the product of its length and width times two. As a linear measurement, the perimeter can be expressed in metres, centimetres, inches, feet, etc.

Perimeter of the rectangle = 2 (l + b) = 2 (21/5 + 30/7)

question 19 has 2 isosceles triangles and the measure of x can be derived by equating one of the base angles of the smaller triangle to the sum of its 2 opposite angles as follows;

let y be one of the base angles of the smaller triangle so that;

2y = 180 - 56 {sum of interior angles of a triangle}

2y = 124

y = 62

hence;

62 = x + x {exterior angle of a triangle equals the sum of its two opposite angles}

2x = 62

x = 31°

For question 20, we first find the two opposite angles of x as follows;

180 -(62 + 50) = 68

180 - (53 + 80) = 47

x = 68 + 47
