What is angle?Angel is a geometric figure that can be described as the amount of rotation between two straight line or planes and angles is measured in degree with the full circle being 360°.
To determine the unknown angle measures of △DEF, we can use the fact that the sum of the angles of a triangle is 180°. Thus, if we know two angle measures in the triangle, we can use them to calculate the third.
Let's denote the two known angle measures as m∠D and m∠F. We can use the following equation to solve for the unknown angle measure:
m∠D + m∠F + m∠E = 180°
We can rearrange the equation to solve for m∠E:
m∠E = 180° - m∠D - m∠F
Therefore, once we know the measures of m∠D and m∠F, we can calculate the measure of m∠E.
For example, if m∠D = 40° and m∠F = 65°, then the measure of m∠E would be:
m∠E = 180° - 40° - 65° = 75°
Therefore, m∠D = 40°, m∠F = 65°, and m∠E = 75°. Round to the nearest degree.

What is constant acceleration equations?
The constant acceleration equations are:
The position equation: x = x0 + v0t + 1/2at^2
The velocity equation: v = v0 + at
The acceleration equation: a = (v - v0)/t
Constant acceleration equations describe the motion of an object that is experiencing a constant acceleration. When an object experiences a constant acceleration, its velocity changes by the same amount in equal time intervals. The equations that describe this motion are as follows:
The position equation: x = x0 + v0t + 1/2at^2
where x is the position of the object at time t, x0 is the initial position of the object, v0 is the initial velocity of the object, a is the constant acceleration of the object, and t is the time elapsed.
The velocity equation: v = v0 + at
where v is the velocity of the object at time t, v0 is the initial velocity of the object, a is the constant acceleration of the object, and t is the time elapsed.
The acceleration equation: a = (v - v0)/t
where a is the constant acceleration of the object, v is the velocity of the object at time t, v0 is the initial velocity of the object, and t is the time elapsed.

Unit conversion is the process of converting the measurement of a given amount between various units, often by multiplicative conversion factors that alter the value of the measured quantity without altering its effects.
The SI base unit of length is the metre (or metre; US spelling), which is denoted by the letter m.
first described in 1793 as a ten millionth of the distance between the equator and the North Pole, but was later redefined in 1799 to refer to a prototype metre bar (this bar was changed again in 1889).
The imperial unit system uses the symbol mi to designate the mile as a unit of length.
Although it was initially an English unit, it was adopted by numerous nations, each of which had a somewhat different definition. However, the English mile is 63,360 inches, 5280 feet, or 1760 yards.

the amount Cody spent on materials, and the 10 represents
the fee to sell at the fair.
If Cody sold 9 scarves at $25 each and spent $34 on
materials, what was his profit, in dollars?
Cody's profit from selling 9 scarves at $25 each, after spending $34 on materials and paying a $10 fee to sell at the craft fair, was $181.
What are mathematical operations?The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.
To calculate Cody's profit using the expression np - (m + 10), we need to substitute the given values:
n = 9 (number of scarves sold)
p = $25 (price per scarf)
m = $34 (amount spent on materials)
Using these values, we can calculate Cody's profit as:
= np - (m + 10)
= (9 * 25) - (34 + 10)
= 225 - 44
= $181
Therefore, Cody's profit from selling 9 scarves at $25 each and spending $34 on materials is $181.

The greatest percent change occurred in the first five-year period, between the first and second year, with a percent change of 60%.
What is percent ?
Percentage is a number or ratio expressed as a fraction of 100.
We can calculate the percent change between two values using the following formula:
percent change = (new value - old value) / old value x 100%
To compare the percent change over a five-year period, we need to consider the percent change between each pair of values, as follows:
Percent change between the first and second year:
percent change = (320 - 200) / 200 x 100% = 60%
Percent change between the second and third year:
percent change = (400 - 320) / 320 x 100% = 25%

what is the 95 % conversion in decimal ?
The 95 % conversion in decimal is 0.95.
To convert a percentage to a decimal, you divide the percentage by 100.
Therefore, to convert 95% to a decimal, you divide 95 by 100:
95 ÷ 100 = 0.95
So, 95% as a decimal is 0.95.
A percentage is a fraction expressed as a fraction of 100 in mathematics. It is frequently used to express percentages, rates, or frequencies in terms of 100. For example, if 95 out of 100 people agree on something, we can express this as a 95% probability.
To convert a percentage to a decimal, simply divide it by 100. The outcome is a number between 0 and 1, with 1 representing the entire (or 100%). In the case of 95%, dividing by 100 yields 0.95 as the decimal equivalent.
Simply multiply a decimal by 100 to convert it to a percentage. To convert 0.95 to a percentage, multiply it by 100 to get:
0.95 x 100 = 95%
As a result, percentages and decimals are two different ways of representing the same value. While percentages are frequently used to express proportions or rates, decimals are frequently used in mathematical computations or scientific notation.

A distribution is a mathematical function that shows the likelihood of different values occurring for a given variable.
Now, a marginal distribution summarizes the information from one variable ONLY, without considering ANY information from another variable. It shows the probability of each value occurring for that variable.
In mathematical terms, we can represent a marginal distribution as follows:
P(X = x) = ∑P(X = x, Y = y) for all possible values of y
Here, X is the variable we're interested in, and Y is the other variable that we're not considering. P(X = x) is the probability of X taking on the value x, and P(X = x, Y = y) is the joint probability of X taking on the value x and Y taking on the value y. The summation is taken over all possible values of y.

Write the tangent ratios for p and q
The answer is: A. tan P= 3/4, tan Q=5/4
Describe trigonometric ratios?Trigonometric ratios are mathematical functions that relate the angles of a right triangle to the ratio of the lengths of its sides. There are three primary trigonometric ratios, known as sine, cosine, and tangent, and their reciprocal functions, known as cosecant, secant, and cotangent.
The primary trigonometric ratios are defined as follows:
Sine (sin): The sine of an angle is the ratio of the length of the opposite side to the length of the hypotenuse of a right triangle.
sin θ = opposite/hypotenuse
Cosine (cos): The cosine of an angle is the ratio of the length of the adjacent side to the length of the hypotenuse of a right triangle.
cos θ = adjacent/hypotenuse
Tangent (tan): The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side of a right triangle.
tan θ = opposite/adjacent
The reciprocal trigonometric ratios are defined as follows:
Cosecant (csc): The cosecant of an angle is the reciprocal of the sine of the angle.
csc θ = 1/sin θ
Secant (sec): The secant of an angle is the reciprocal of the cosine of the angle.
sec θ = 1/cos θ
Cotangent (cot): The cotangent of an angle is the reciprocal of the tangent of the angle.
cot θ = 1/tan θ
Trigonometric ratios are widely used in mathematics, science, and engineering to solve problems involving right triangles, as well as to model and analyze periodic phenomena such as sound waves, light waves, and electromagnetic waves.
Since angle R is a right angle, we can use the tangent ratio for angles P and Q as follows:
tan P = RP / RQ = 12 / 16 = 3 / 4
tan Q = PQ / RQ = 20 / 16 = 5 / 4
