As per the given triangles given in the question, the corresponding names are mentioned accordingly in the answer.
How do triangles work?A triangle is a basic polygonal geometry with three sides and three interior angles. This is a fundamental geometric shape that is particularly related. Its three vertices are joined together. Depending on their sides and angles, triangles can be classified into a wide range of groups.
In geometry, there are six different kinds of triangles. There are two categories into which they can be divided. The three triangles are categorized as equilateral triangles, isosceles triangles, and scalene triangles based on their sides. Triangles can be classified as acute, obtuse, or right-angled depending on the angle at which they are formed. There are so six different kinds of triangles in geometry.

Based on the given triangle, we can find that:
The length of PN is 11The length of GN 37The size of angle ∠GLN is 32First, we will focus on the triangle NLP. NLP is a right triangle, then we can use the formula of sinus to find the length of NP, where:
Sin ∠NLP = NP / LP
Sin 35° = NP / 20
0.57 = NP / 20
NP = 11.47
NP ≈ 11
Next, we will focus on triangle GLP. GLP is a right triangle with hypotenuse of 52 and the base of 20. Using the Phytagoras theorem we can try to find the triangle's height.
GL² = GP² + LP²
52² = GP² + 20²
2704 = GP² + 400
GP² = 2304
GP = 48
GP = GN + NP
48 = GN + 11
GN = 37
To find the size of angle ∠GLN, we have to find the size of angle ∠PGN first. We will use the Sines Law:
LP / sin ∠PGN = GL / sin ∠GPN
20 / sin ∠PGN = 52 / 1
sin ∠PGN = 20/52
∠PGN = 22.5°
∠PGN ≈ 23°
∠GLP + ∠GPL + ∠PGN = 180°
∠GLP + 90° + 23° = 180°
∠GLP = 67°
∠GLP = ∠GLN + ∠NLP
67° = ∠GLN + 35°
∠GLN = 32°

kenia wants to buy a $75.00 skateboard. She has 25.00 saved so far. she mows lawns to make extra money and earns 20.00 for each lawn she mows. Which inequality can be used to determine the number of lawns, x, she needs to mow to have enough money to buy the skateboard
Step-by-step explanation:
75.00 - 25.00 = 50.00
50.00 / 20.00 = 2.50
So, she needs to mow 2.5 lawns or more to have enough money to buy the skateboard.
The inequality can be expressed as:
20.00 * x >= 50.00
x >= 2.50
So, the inequality "x >= 2.50" can be used to determine the number of lawns she needs to mow to have enough money to buy the skateboard.

Answer:
B) Linear Pair
D) Adjacent
E) Supplementary
Step-by-step explanation:
Because the sum of the two angles is 180°, we conclude that the correct options are:
B, D, and E.
Which is the relationship between the two angles?We want to find the relationship between angles a and b.
Notice that if we would add these two angles, we would get a plane angle, then we could write:
∠a + ∠b = 180°.
That means 3 things:
The angles are adjacent because share a vertex and a common side, and the angles are supplementary because their sum is equal to 180°, and also are a linear pair, because their sum is equal to 180°.
Then the correct options are:
B, D, and E.

let y1,y2 be independent random variables both having the uniform(0,1) distribution. re- call that the density function and distribution function of a uniform random variable y
A uniform random variable's density function is f(y) = 1 for y 1 and 0 otherwise. F(y) = 0 for y 0, F(y) = y for 0 y 1, and F(y) = 1 for y > 1 define the distribution function.
A uniform random variable's density function is f(y) = 1 for y 1 and 0 otherwise. Accordingly, the likelihood of any specific outcome of y is the same, and the likelihood of any range of outcomes is equal to the length of the range. F(y) = 0 for y 0, F(y) = y for 0 y 1, and F(y) = 1 for y > 1 define the distribution function. Accordingly, the length of the range multiplied by the likelihood of any specific occurrence yields the cumulative probability of any range of outcomes. Since the likelihood of any specific result in that range is 1 and the range's length is 0.5, for instance, the cumulative probability of 0 y 0.5 is 0.5. Since the likelihood of any given result within that range is still 1, but the range's length is 0.5, the cumulative probability of 0.5 y 1 is 0.75. The chance of any range of outcomes for y1 and y2 if they are independent random variables both having the uniform(0,1) distribution is just the sum of their respective cumulative probabilities.

It may alternatively be described as a hexagon that is basic rule, or one in which all of the angles are equal. A straight angle is another another option for the parallelogram. In a square, four of the vertices are the same length. A quadrilateral with a rectangle-shaped cross section has four 90 ° angle vertices + equal parallel sides. As a result, it is sometimes referred to as a "equirectangular rectangle". Due to such equal and parallel dimensions of its two sides, a rectangle is occasionally referred to as parallelogram.
The left rectangle has a height of 18 ft and a width of 21 ft, so its area is:

Answer:
Step-by-step explanation:
Quadratic X €
Evaluate -20
Answer:
[tex]x=\frac{1}{2} \pm \frac{i\sqrt{5}}{2}[/tex]
Step-by-step explanation:
Lets solve for [tex]x[/tex] in
[tex]-2^2-2x^2+2x+1=0[/tex]
Evaluate [tex]2^2[/tex]
[tex]-4-2x^2+2x+1=0[/tex]
Add [tex]-4[/tex] and [tex]1[/tex].
[tex]-2x^2+2x-3=0[/tex]
Divide both sides of the equation by [tex]-2[/tex].
[tex]x^2-x+\frac{3}{2}=0[/tex]
Now the equation is in standard form.
[tex]ax^2+bx+c=0[/tex]
We can solve this quadratic by completing the square.
Subtract [tex]\frac{3}{2}[/tex] from both sides of the equation.
[tex]x^2-x=-\frac{3}{2}[/tex]
Take one half of the coefficient of [tex]x[/tex] and square it, then add it to both sides.
Add [tex]\frac{1}{4}[/tex] to both sides.
[tex]x^2-x+\frac{1}{4} =-\frac{3}{2}+\frac{1}{4}[/tex]
[tex]x^2-x+\frac{1}{4} =-\frac{5}{4}[/tex]
The left hand side is a perfect trinomial square.
Factor the left hand side by writing it as a square.
[tex]\left(x-\frac{1}{2}\right)^2 =-\frac{5}{4}[/tex]
Take the square root of both sides to eliminate the exponent.
[tex]x-\frac{1}{2} =\pm\sqrt{-\frac{5}{4}}[/tex]
Rewrite [tex]\frac{5}{4}[/tex] as [tex]\left(\frac{i}{2} \right)^2 *5[/tex]
[tex]x-\frac{1}{2} =\pm\sqrt{\left(\frac{i}{2} \right)^2 *5}[/tex]
Pull terms out from under the radical.
[tex]x-\frac{1}{2} =\pm \frac{i}{2} \sqrt{5}[/tex]
Combine [tex]\frac{i}{2}[/tex] and [tex]\sqrt5[/tex].
[tex]x-\frac{1}{2} =\pm \frac{i\sqrt{5}}{2}[/tex]
Add [tex]\frac{1}{2}[/tex] to both sides of the equation.

Let AA be the event that a randomly selected IRSC student is an Associate of Arts student and
P(AA) = 0.41. Let the event PM be the event that a randomly selected IRSC student is on the pre-med
degree track and P(PM) = 0.38. Finally, the probability that a randomly selected IRSC student is an AA degree seeker and on the pre-med degree track is 0.05. Use this information to calculate the following
probability.
Answer:
P(AA) = 0.41
P(PM) = 0.38
P(AA and PM) = 0.05
As you are finding P(AA or PM), you can apply the formula:
P(A U B) = P(A) + P(B) - P( A ∩ B)
U = Union P( A U B) = P (A or B)
∩ = And
From the formula, you can find out the answer:
P(AA or PM) = P(AA) + P(PM) - P(AA and PM)
= 0.41+0.38-0.05

if f(x) is discontinuous, determine the reason. f of x equals the quantity x squared plus 4 for x less than 1 and equals x plus 4 for x greater than 1
The two equations for f(x) are not equal at x = 1 and f(x) is therefore discontinuous at this point
f(x) is discontinuous at x = 1 because when x = 1, the two separate equations for f(x) do not have the same output. For x < 1, [tex]f(x) = x^2 + 4[/tex], so when x = 1, [tex]f(1) = 1^2 + 4 = 5. For x > 1, f(x) = x + 4[/tex] , so when x = 1, f(1) = 1 + 4 = 5. The output of f(1) is different on each side of the discontinuity. This can be seen in the following calculation:
For x < 1,
[tex]f(x) = x^2 + 4f(1) = 1^2 + 4 = 5For x > 1,f(x) = x + 4f(1) = 1 + 4 = 5[/tex]
Since f(1) is 5 for x < 1 and f(1) is also 5 for x > 1, the two equations for f(x) are not equal at x = 1 and f(x) is therefore discontinuous at this point.
