The value of GL is 161.We can find by using supplementary angles.

Supplementary angles are those angles that sum up to 180 degrees. For example angle 130° and angle 50° are supplementary angles because sum of 130° and 50° is equal to 180°.There are a total of two supplementary quantities and their units.

The sum of two angles is equal to 180° then they are supplementary angles. Each of the angles is said to be a supplement of another angle. Hence we can determine the supplement of an angle by subtracting it from 180°.

Now

According to supplementary angles

GL + LK =180

GL         =180- LK

GL         = 180 -19

GL      = 161

Using the concept of arithmetic progression , We have t(n) = a +(n-1)d formula, The answer is 3.

A number sequence is a series of numbers that are listed in a particular order. The numbers in a sequence may follow a specific pattern or rule. Examples of number sequences include the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13, 21, etc.), the Fibonacci sequence (1, 2, 4, 8, 16, 32, etc.), and the triangular number sequence (1, 3, 6, 10, 15, etc.). Number sequences are often studied in mathematics and have many applications in fields such as computer science, engineering, and physics.

An arithmetic progression (AP) is a type of number sequence in which the difference between any two consecutive terms is always the same. This common difference is known as the "common ratio" of the sequence. For example, the sequence 2, 5, 8, 11, 14 is an arithmetic progression because the common difference is 3.

Solving the triangle we found the distance between the gazebo and the dock is: 69.34 meters. The answer is explained below:

The first thing to know is that to solve any triangle you must know at least one side and two other elements that can be sides or angles, that is, at least three elements of the six that make up a triangle.

Now, in the problem we know the value of one side (90 m) and 3 angles (see attached image), therefore the calculation of the distance (one side) is very easy if we apply the law of sines:

According to the Law of Sines, the ratio of the length of the sides of a triangle (not a rectangle) and their respective opposite angle sines, is the same value. Then:

d / sen (46°) = 90 m / sen (69 °)  

After, we pass  sen (46°) to the second term of the equation.

d= sen(46°)*90 m / sen (69°)

d = 0,7193*90/ 0,9335

d = 69,34 m

A triangular prism is a three-dimensional shape with two triangular faces and three rectangular faces. It is also known as a tetrahedron, which is a type of polyhedron with four faces. The triangular prism has a total of six faces and nine edges.

The formula of surface area of triangular prism is given as;

S.A = 2A + PH

The base area of the prism is given as;

A = 1/2 (b * h)

A = 1/2 * (9 * 14)

On solving the question we can say that  slope intercept form of the equation is y = -1/4x +1/2

One of the most popular ways to describe a line's equation is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope intercept formula may be used to get the equation of a line ( the y-coordinate of the point where the line intersects the y-axis). The equation of a line is the equation that each point on the line fulfills.

The slope intercept form is a technique for figuring out a straight line's equation in the coordinate plane. Any point's coordinates on a straight line must fulfill a certain relation, which is known as the equation of a straight line.

Any location that is not on the line will not fulfill the coordinates.

This equation's solution is simple to find. A straight line's slope, or angle of inclination from the x-axis, and the intercept it makes with the y-axis are both necessary to determine the slope intercept form of the line.

The line passes through (-2,1)

slope = -1/4

The equation of the line

y = mx + c

here m is the slope and c is the intercept.

putting the point and slope in the equation

1 = -1/4 *(-2) + c

⇒ c = 1/2

So the slope intercept form of the equation is

y = -1/4x +1/2

The line that connects the coordinates (6, 4) and is perpendicular to the line 2xy=5 has the equation =y=1/2x-1.

The general equation for every straight line is y = mx + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y-axis).

The variables x and y are related to coordinates on the line in the linear equation y = mx + c.

The formula y = mx + c yields a result for y when we enter a value for x.

As y depends on the value of x, it follows that x is an independent variable and y is a dependent variable.

To find the average speed of the passenger jet, we need to divide the distance traveled by the time it took to travel that distance.

Average speed = distance / time

In this case, the distance is 1,213 miles and the time is 2.7 h.

Average speed = 1213 miles / 2.7 h = 449.6 miles/h

So the average speed of the passenger jet is 449.6 miles per hour.

The relationship between the interior and exterior angles of a polygon is they are supplementary.

What is a regular polygon?

If a polygon has equal sides and angles, it is said to be regular. As a result, an equilateral triangle is a regular triangle, and a square is a regular quadrilateral.

Here,

we have to show how the interior and exterior angles of a polygon relate to each other.

A special rule exists for regular polygons: because they are equiangular, the exterior angles are also congruent, so the measure of any given exterior angle is 360/n degrees.

As a result, the interior angles of a regular polygon are all equal to 180 degrees minus the measure of the exterior angle(s).

Hence, the relationship between the interior and exterior angles of a polygon is they are supplementary.

According to the information, the sets of ingredients that have a proportional relationship with the original recipe are: option A, C and D.

To check the proportional relationship of the ingredients with the recipe we must carry out the following procedure.

Option A.

First, we need to establish how many times 6 is in 12 because this recipe includes 6 parts oil and the original recipe includes 12 parts oil.

Once we identify this number, we must divide the amounts of the original recipe by 2 to identify if the other values are correct.

In accordance with the above, option 1 would be proportional to the main recipe. For the other options we must perform the same procedure:

In the case of case C. we identify that 24 is twice 12, so we would have to multiply each ingredient by 2 to check the proportional relationship

In the last case (option D), we identify that the proportion is 3/4 with respect to the original recipe, so we must carry out the same procedure keeping this proportion in mind.
