1. How does radian measure of an angle compare to the degree measure? Include an explanation of 1 radian in your answer.
2. Explain how the cosine of an angle in the second quadrant differs from the cosine of its reference angle in the unit circle.
3. Describe the secant and cosecant functions.
4. When a right triangle with a hypotenuse of 1 is placed in the unit circle, which sides of the triangle correspond to the x- and y-coordinates?
Through the knowledge and trigonometry, we have :
1 radian = 180 degrees[tex]t^{'} = 180-t[/tex][tex]Secant \alpha = \frac{hypotenuse}{base}\\ Cosecant \alpha = \frac{hypotenuse}{perpendicular}[/tex]The x-coordinate is the central angle's adjacent side, while the y-coordinate is its opposite side.1. Since a circle's circumference is 360 degrees or two pi radians, a radian is equivalent to 180 degrees. Since radians require knowledge of higher mathematics and contain tangents, sines, and cosines, which are taught in college, they are not as frequently employed in measuring circles and angles as degrees.
2. The measurement of the lowest, positive, acute angle t created by the angle's terminal side is known as the reference angle, t the horizontal axis, too. As a result, positive reference angles can be used as models for angles in other quadrants because their terminal sides are in the first quadrant.
In the 1st Quadrant, All the trigonometric functions are positive,
[tex]t^{'} =t[/tex]
In the 2nd Quadrant. Only Sin is positive,
[tex]t^{'} = 180-t[/tex]
So, [tex]cost^{'} = Cos(180-t) = -Sint[/tex]
3. Secant is the Inverse of Cos and Cosecant is the Inverse of Sine, Hence they are :
[tex]Secant \alpha = \frac{hypotenuse}{base}\\ Cosecant \alpha = \frac{hypotenuse}{perpendicular}[/tex]
4. The x-coordinate is the central angle's adjacent side, while the y-coordinate is its opposite side.

Bags A and B each contain counters.
Bag A
60 counters
Each counter is green, blue or yellow
P(green counter from A) = P(red counter from B)
Work out the number of green counters in A.
Bag B
12 counters
9 blue and 3 red
In probability, A is 8 out of 16 and C is 3 out of 15.
What is probability explain?
The likelihood or chance that a specific event will occur is represented by a probability. Both proportions between 0 and 1 and percentages between 0% and 100% can be used to describe probabilities.Out of the 17 counters in the bag 3 are yellow , 6 are red and the rest i.e., 17–3–6 or 8 nos.are green.
When selected randomly once one counter the probability of selecting one is
A. green is 8 out of 17 or 8/17 ,
B. getting a red one is 6 out of 17 or 6/17.
C. getting a yellow is 3 out of 17.
This is when the counter is put back in the bag for selecting.
If the selected one is not put back remaing counters are less by one each time it's drawn and then the probability figure is one out of 16 in the second case and one out of 15 for the third draw ime., then A is 8 out of 16 and C is 3 out of 15.

Find the length of CD.express the awnser as a fraction times pie.
Given the figure of the circle B
the radius of the circle = r = BC = 9
the measure of the angle CBD = 40°
We will find the length of the arc CD
The length of the arc is given by the formula:
[tex]l=\theta\cdot r[/tex]where: θ is the central angle opposite to the arc measured in radians
so, we will convert the given angle from degree to radian
[tex]\theta=40\cdot\frac{\pi}{180}=\frac{2}{9}\pi[/tex]Substitute with the given values
so, the length of the arc =
[tex]l=\frac{2}{9}\pi\cdot9=2\pi[/tex]So, the answer will be:

A s’mores maker kit has a list price of $39.95 and is offered to wholesalers with a series discount of 20/10/10. The same appliance is offered to Kitchen Crafters (a retailer) with a series discount of 20/10. Find the difference in price.
Since the list price is $39.95
Since the series of discounts 20/10/10
Then we will find the new price by this way
Since the first discount is 20%, then
The new price will be 80% of 39.95
[tex]\frac{80}{100}\times39.95=31.96[/tex]Since the second discount is 10%
Then the new price is 90% of 31.96
[tex]\frac{90}{100}\times31.96=28.764[/tex]Since the third discount is 10%
Then the new price is 90% of 28.764
[tex]\frac{90}{100}\times28.764=25.8876[/tex]Since the second option has only a 20/10 discount, then
The new price is 28.764
To find the difference subtract 25.8876 from 28.764
The difference = 28.764 - 25.8876
The difference = 2.8764
The answer is $2.8764

So, we know BC is parallel to EF and 1 is congruent to 3.
Angles between parallel lines have special relationships. The relationships between 2 and 3 is that they are Same-side Interior Angles. This means that angles on the same line, formed by parallel lines intersecting that line (and the angles are on the same side of their respective line) are congruent. So, 2 and 3 are congruent... But by the transitive property, if 1 = 3 and 3 = 2... 1 = 2! And if 1 = 2, they are also Same-side interior angles and thus, the lines they lie on are parallel! So, since 1 and 2 are congruent, AB is parallel to DE.
Answer:
See below.
Step-by-step explanation:
Corresponding Angles Postulate
When a straight line intersects two parallel straight lines, the resulting corresponding angles are congruent.
[tex]\begin{array}{c|c}\sf Statement & \sf Reason\\\cline{1-2} BC \parallel EF & \phantom{\dfrac11}\sf Given\\\\\angle 2=\angle 3 & \textsf{Corresponding Angles Postulate}\\\\\angle 1=\angle 3 & \sf Given\\\\\angle 1=\angle 2 & \textsf{Transitive property of equality}\\&(\angle 2=\angle 3 \; \textsf{and} \; \angle 1=\angle 3)\\\\AB \parallel DE & \textsf{Corresponding Angles Postulate}\\& \textsf{as} \;\angle 1=\angle 2\end{array}[/tex]
As DE intersects the two parallel lines BC and EF, ∠2 is congruent to ∠3 (corresponding angles postulate).
As ∠1 = ∠3 and ∠2 = ∠3, then ∠1 = ∠2 (transitive property of equality).
Therefore, as ∠1 and ∠2 are congruent, AB and DE must be parallel (BC is the transversal).

A circle of radius r has area A, where A =xr^2
The area A of the circle whose radius is 10 can be calculated by given equation A =pi r^2 is 314.2 cm^2.
What is area?
Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape.
If we draw a square using a pencil on a sheet of paper. It will have two dimensions. The area of a shape on paper is the area that it occupies and it will be called as area of that square.
For getting the area of the circle we need to put the value of r in the given equation:
r = 10 cm
Putting the value of pi and r in the equation:
A = pi r^2
A = 3.142 (10)^2
A = 3.142 (100)
A = 314.2

If n represents the number of nickels in the jar, what equation could you use to find n?
__ of the coins are not nickels.
Answer:"There are 24 pennies, 21 dimes, and 29 quarters", so there are 25+21+29 = 75 coins so far. This is the amount of coins that aren't nickels. The rest are nickels, which is some amount n. This adds to the 75 to get 75+n. Set this equal to 92 because there are 92 coins in all. That's how we end up with 75+n = 92.

The equation 75+n = 92 is the same as n+75 = 92. Subtract 75 from both sides to isolate n. You should get n = 17 after doing so.
