The value of angles are,
∠ H = 20°
∠ G = 100°
∠ I = 60°
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Two triangles are similar.
Now, We have in triangle XYZ,
∠Y = 20°
∠Z = 100°
Hence, ∠ X = 180 - (100 + 20)
∠ X = 60°
Thus, By definition of similarity;
∠ H = ∠ Y = 20°
∠ G = ∠ Z = 100°
∠ X = ∠ I = 60°
Thus, The value of angles are,
∠ H = 20°
∠ G = 100°
∠ I = 60°

Since [tex]1 - \sin^{2}{\theta} = \cos^{2}{\theta}[/tex], the trigonometric expression [tex]\frac{\sin{\theta}}{\sqrt{1 - \sin^{2}{\theta}}} = \tan{\theta}[/tex] is proven.
How to prove the trigonometric expression?The trigonometric expression for this problem is defined as follows:
[tex]\frac{\sin{\theta}}{\sqrt{1 - \sin^{2}{\theta}}} = \tan{\theta}[/tex]
The identity used for the proof is given as follows:
[tex]\sin^{2}{\theta} + \cos^{2}{\theta} = 1[/tex]
Hence:
[tex]1 - \sin^{2}{\theta} = \cos^{2}{\theta}[/tex]
Replacing on the left side of the expression, we have that:
[tex]\frac{\sin{\theta}}{\sqrt{1 - \sin^{2}{\theta}}} = \frac{\sin{\theta}}{\sqrt{cos^{2}{\theta}}}[/tex]
Taking the square root:
[tex]\frac{\sin{\theta}}{\sqrt{1 - \sin^{2}{\theta}}} = \frac{\sin{\theta}}{\cos{\theta}}[/tex]
The tangent is given as the division of the sine by the cosine, hence:

The following compositions are shown below:
Case 1
f ° g (x) = x, g ° f (x) = x
The two functions are inverses of each other.
Case 2
f ° g (x) = x, g ° f (x) = x
The two functions are inverses of each other.
How to find the composition between two functions and determine if the two functions are inverses or not
In this problem we need to determine the composition between two functions and determine if both functions are inverses of each other. A composition is defined below:
f ° g (x) = f [g (x)]
Where the independent variable of the function f(x) is substituted by function g(x). Two functions are inverses if and only if the following condition is fulfilled:
f[g (x)] = g[f (x)]
Now we proceed to determine the compositions and relationships for each case:
Case 1
f(x) = 3 · x
g(x) = x / 3
f ° g (x) = 3 · (x / 3)
f ° g (x) = x
g ° f (x) = (3 · x) / 3
g ° f (x) = x
Functions f(x) and g(x) are inverses of each other.
Case 2
f(x) = (x - 3) / 2
g(x) = 2 · x + 3
f ° g (x) = [(2 · x + 3) - 3] / 2
f ° g (x) = 2 · x / 2
f ° g (x) = x
g ° f (x) = 2 · [(x - 3) / 2] + 3
g ° f (x) = (x - 3) + 3
g ° f (x) = x
Functions f(x) and g(x) are inverses of each other.

Why is the lac curve called the envelope curve?
The lac curve, also known as the envelope curve, is a curve that shows the maximum amount of work that can be done in a given period of time.
It is defined by the equation: W = min {W1 + W2, W3, W4, ..., Wn}, where W1, W2, W3, W4, ..., and Wn are the individual work tasks. The envelope curve is called such because it forms an envelope that encompasses all of the individual tasks on the graph, visually representing the maximum amount of work that can be done within the given timeline. This curve can be used to assess the efficiency of a task or project, as well as to analyze the impact of changes in the workload, deadlines, and resources.

What is 76 degree F in C?
76 degrees Fahrenheit was found to be equal to approximately 24.4 degrees Celsius using the formula of conversion.
To convert Fahrenheit to Celsius, you can use the following formula:
Celsius = (Fahrenheit - 32) x 5/9
Plugging in 76 degrees Fahrenheit, we get:
Celsius = (76 - 32) x 5/9
Celsius = 44 x 5/9
Celsius = 220/9
Celsius ≈ 24.4
Therefore, 76 degrees Fahrenheit is approximately 24.4 degrees Celsius.
On the Fahrenheit scale, water freezes at 32 degrees Fahrenheit (°F) and boils at 212 °F, at standard atmospheric pressure.
On the Celsius scale, the freezing point of water is defined as 0 degrees Celsius (°C), and the boiling point of water is defined as 100 °C, at standard atmospheric pressure.

which one of the following best describes the notion of the significance level of a hypothesis test?The probability of observing a sample statistic more extreme than the one actually obtained, assuming the null hypothesis is true
The probability of the type I error
The probability of the type II error
The Hypothesis test of probability of the type I error is True.
The Hypothesis test probability of the type II error is False.
The notion of the significance level of a hypothesis test is best described by the probability of observing a sample statistic more extreme than the one actually obtained, assuming the null hypothesis is true. This is also known as the "p-value." A significance level is often set beforehand, such as alpha (α) = 0.05, and if the p-value is less than alpha, the null hypothesis is rejected.
The probability of a type I error is related to the significance level. A type I error occurs when the null hypothesis is rejected when it is actually true. The probability of a type I error is represented by alpha (α) and is the level of significance that was set for the test.
The probability of a type II error is the probability of failing to reject a false null hypothesis. It is represented by beta (β) and depends on the sample size, the true value of the parameter being tested, and the level of significance set for the test.

If m∠A = 50° and m∠B = 45°, what is m∠H?
(If anyone knows all the answer to any of these please provide a link.)
(It's called Chapter 5 Test, 3B Ratio, Proportion, and Similar Figures)
The measure of m∠H in the triangle is 85°.
How to find the measure of m∠H?
Similar triangles are two triangles that have the same shape but can have different sizes. More specifically, two triangles are similar if their corresponding angles are congruent and their corresponding sides are proportional.
Since ΔABC and ΔFGH are similar, we can say:
m∠A = m∠F
m∠B = m∠G
m∠C = m∠H
m∠A + m∠B + m∠C = 180° (sum of angles in a triangle)
We have m∠A = 50° and m∠B = 45°
50° + 45° + m∠C = 180°
m∠C = 180° - 50° - 45°
m∠C = 85°
Since m∠C = m∠H
Thus, m∠H = 85°

Plug in values: [tex]-1=-\frac{1}{4} (-8)-3[/tex]
Multiply: [tex]-1=2-3[/tex]

Plug in values:[tex]-4=-\frac{1}{4} (4)-3[/tex]
Multiply: [tex]-4=-1-3[/tex]
Subtract: [tex]-4=-4[/tex]
Notice that we now have a false expression, therefore option "d" IS A SOLUTION, and is thus not the correct answer.

A $1000 cash inflows at the end of each year would have a future value of $8,142.01, $8,922.80 and $11.772012 at the end of the year 7 for interest rates of 5% , 8% and 17% respectively.
Future Value:Annuities are a financial instrument that generates a regular stream of cash. They have both a present and future value dependent upon the value of the cash payment, the number of payment periods and the interest rate. This question does not specify the cash inflow amount so an answer will be generated that can be scaled on multiples of $1000.
Let C represent the cash inflow at the end of each year. The future value (FV) of this cash inflow is given by:
FV = [tex]C[((1+i)^n-1)/i][/tex]
where i is the annual interest rate and n is the number of years.
(a) For i = 5% and n = 7
FV = [tex]C [((1+0.05)^7-1)/0.05][/tex]
FV= C[(1.047100-1)/0.05]
FV = C [8.142008]
(b) For i = 8% and n = 7
FV = [tex]C [((1+0.08)^7-1)/0.08][/tex]
FV = C[(1.713824 - 1)/0.08]
FV = C[8.922803]
(c) For i = 17% and n = 7
FV = [tex]C [((1+0.17)^7-1)/0.17][/tex]
FV = C[(3.001242 - 1)/ 0.17]
FV = C[11.772012]
Therefore, A $1000 cash inflows at the end of each year would have a future value of $8,142.01, $8,922.80 and $11.772012 at the end of the year 7 for interest rates of 5% , 8% and 17% respectively.

mangleD =

mangleDEC
The Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the 2 nonadjacent interior angles. That means that the measure of angle DEF is equal to the sum of measure of angle C and measure of angle D. Substituting known values gives you 2y + 9 + 6y + 10 = 115, then you can solve
8y + 19 = 115
8y = 96
y = 12
The measure of angle C is 33 degrees, the measure of angle D is 82 degrees, and because the measure of angle DEF is 115 degrees, its supplement angle (DEC) measures 65 degrees.

Two triangles that are identical in size and shape are said to be congruent triangles.
