The measure of angle x and y in the cyclic quadrilateral are 93 and 59 degrees.

A cyclic quadrilateral is a quadrilateral which has all its four vertices lying on a circle. The sum of angles in a cyclic quadrilateral is 360 degrees.

The opposite angles in a cyclic quadrilateral add up to 180°. The opposite angles of a cyclic quadrilateral are supplementary.

Therefore, let's find the measure of x and y in the cyclic quadrilateral.

Hence,

x + 87 = 180

x = 180 - 87

x = 93 degrees

y + 121 = 180

y = 180 - 121

y = 59 degrees

Therefore,

x = 93°

y = 59°

The sum of the units 3 ft. 9 in, 4 ft. 7 in. and  10 ft. 3 in. is 18 ft. 7 in.

To add these lengths, we need to first convert all the measurements to the same units.

Let's convert everything to inches.

3 ft. 9 in. = (3 x 12) + 9 = 45 in.

4 ft. 7 in. = (4 x 12) + 7 = 55 in.

10 ft. 3 in. = (10 x 12) + 3 = 123 in.

Now we can add the lengths:

45 in. + 55 in. + 123 in. = 223 in.

We have 223 inches in total.

To convert this back to feet and inches, we can divide by 12 to get:

18 ft. 7 in.

So the final answer is 18 ft. 7 in.

In Linear equation, 5/8 golf balls per ounce are the number of golf balls per Ounce.

What in mathematics is a linear equation?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

                          Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables. Equations with power 1 variables are known as linear equations. One example with only one variable is where ax+b = 0, where a and b are real values and x is the variable.

Number of golf balls (n) = 20

Total weight (w) = 32 ounces

total weight = number of balls (n) * weight of 1 golf ball

∴ weight of 1 golf ball = w/n =32/20 ounces

⇒ the weight distribution is 1.6 ounce per golf ball

Now, apply unitary method :

32 ounces is total weight of 20 golf balls

∴ 1 ounce amounts to 20/32 golf balls

The angle measures that satisfy cos theta = 1/2 are

To find all angle measures for which cos theta = 1/2, we can use the unit circle and look for the x-coordinate of the point where the angle intersects the unit circle.

The x-coordinate (cosine) is equal to 1/2 at two points on the unit circle:

However, the given angle measures are not all within one revolution (360 degrees or 2pi radians), so we need to find equivalent angles within one revolution.

To do this, we can add or subtract multiples of 360 degrees or 2pi radians from the given angles until they are within one revolution.

-120° = 360° - 120° = 240°

-60° = 360° - 60° = 300°

120° = 120°

600° = 600° - 1(360°) = 240°

660° = 660° - 2(360°) = 60°

So the angle measures that satisfy cos theta = 1/2 are -120° (or 240°), -60° (or 300°), and 660° (or 60°).

A negative answer makes no sense because y is an angle and cannot be negative. As a result, we can conclude that there is no solution because the specified angles do not form a proper triangle.

A triangle is a closed, double-symmetrical shape composed of three line segments known as sides that intersect at three places known as vertices. Triangles are distinguished by their sides and angles. Triangles can be equilateral (all factions equal), isosceles, or scalene based on their sides. Triangles are classified as acute (all angles are fewer than 90 degrees), good (one angle is equal to 90 degrees), or orbicular (all angles are higher than 90 degrees) (all angles greater than 90 degrees). The region of a triangle can be calculated using the formula A = (1/2)bh, where an is the neighbourhood, b is the triangle's base, and h is the triangle's height.

The total of a triangle's angles is 180 degrees. As a result, we may begin by locating the missing angle in the triangle containing the angle denoted by y:

Angle missing = 180° - 40° - y = 140° - y

y + 160° + 30° = 180°

Mixing like terms and calculating y:

y = 180° - 160° - 30° = -10°

A negative answer makes no sense because y is an angle and cannot be negative. As a result, we can conclude that there is no solution because the specified angles do not form a proper triangle.

The two sides of the triangle are equal the triangle is an isosceles triangle.

Triangles with two equal sides are known as isosceles triangles. Triangles are three-sided polygons that can be categorised as equilateral, isosceles, or scalene depending on how long their sides are.

The uneven side of this triangle is referred to as the base since the other two sides are equal in it. The triangle's two equal sides are always opposing equal angles. An isosceles triangle's height is calculated from its base to its vertex (topmost point). The third angle of a right isosceles triangle is 90 degrees.

The coordinates of the triangle are J(-2, 4), K(8, 4) and L (6, -2).

Using the distance formula we have:

The distance between J and K: √((8 - (-2))² + (4 - 4)²) = 10

The distance between K and L: √((6 - 8)² + (-2 - 4)²) = 6.324

The distance between L and J: √((-2 - 6)² + (4 - (-2))²) = 10

Point (D) (-7, 4) must be on the graph of the inverse function F¹(x)  if point (7,-4) is on the graph of the function F(x).

If there is just one value of x in the domain where f(x)=y, then a function f does not have an inverse function.

The term "f inverse" is widely used to refer to this particular inverse function, which is singular.

A function's inverse will cause the input and output to be inverted.

If a function has an inverse, one can use algebra to find it by setting the function equal to y.

Then, swap x and y and solve for y in terms of x.

So, we have the coordinates:
(7, -4)

It lies in the 4th quadrant.

Then, its inverse would be in the 2nd quadrant.

Answer:

Step-by-step explanation:

To find the value of x in the triangle, we can use the law of sines, which states that in any triangle ABC, the following relationship holds:

a/sin A = b/sin B = c/sin C

where a, b, and c are the side lengths of the triangle opposite to the angles A, B, and C, respectively.

In this case, we can write:

x/sin 80° = 7/sin 50°

Using the properties of sines, we can simplify this expression to:

x = (7 x sin 80°) / sin 50°

Using a calculator, we can evaluate this expression to get:

x ≈ 9.05

Therefore, the value of x in the triangle is approximately 9.05.

bh, where b is the base and h is the height of the parallelogram.

In the case of the circle, the base of the parallelogram is the circumference of the circle, which is equal to 2πr, where r is the radius of the circle. The height of the parallelogram is the distance from the center of the circle to the edge of the circle, which is also the radius r. Therefore, we have:

b = 2πr

h = r

Substituting these values into the formula for the area of a parallelogram, we get:

Area = bh = (2πr)(r) = 2πr^2

So the formula for the area of a circle is derived from the formula for the area of a parallelogram by using the circumference of the circle as the base and the radius of the circle as the height.

Based on proportions, the numbers of students in the senior form and junior form are 615 and 885, respectively.

Proportion refers to the equation of two ratios.

Proportion is a fractional value depicted using ratios, percentages, fractions, and decimals.

The percentage of senior form students in the school = 41%

The percentage of junior form students = 59% (100% - 41%)

The additional percentage of junior over senior students = 18% (59% - 41%)

The additional number of junior form students over the seniors = 270

Proportionately, if 18% = 270, the total number of students (both junior and senior) = 1,500.

Therefore, the number of senior and junior students is as follows:

Check:

The difference in the numbers = 270 (885 - 615)

The solution of the inequality is 7 < x < 13 and graph is attached.

The inequality 5 < x - 2 < 11 represents a range of values for x that satisfy the inequality. To graph its solution, we can start by adding 2 to each part of the inequality:

5 + 2 < x - 2 + 2 < 11 + 2

This will be simplified to:

7 < x < 13

This solution represents all values of x that make the inequality true. To graph this on a number line, we can draw a line with a point at 7 and a point at 13, and shade in the region between them. The shaded region represents all values of x that satisfy the inequality.

In words, the solution can be described as follows: x is greater than 7 and less than 13. Alternatively, we can use interval notation to represent the solution as (7, 13).

It is important to note that the solution to the inequality is not a single value, but rather a range of values. The graph helps to visualize this range and make it easier to understand.
