Answer:

Step-by-step explanation:

Part b: Find the length of the sidewalk. The walk is the hypotenuse of a right 30-60-90 triangle with horizontal side 2√3. Using the 30° angle as the reference angle, we get the following from the definition of the cosine function:

cos 30° = adj / hyp, or:

√3 2√3

------- = --------

2 hyp

This simplifies to

1 2

-------- = -------

2 hyp

Cross multiplying results in: hyp = 4. The sidewalk length is 4 miles.

a. The width of the park can be found using the sine function, the now-known hypotenuse and the 30° angle:

1 opposite side

sin 30 degrees = ----- = ------------------------- or 2(opp side) = 4.

2 4

Then the opp side, which is the width of the park, is 2.

PLSS HELP MEEE IVE BEEN TRYING ALL DAY TO GET THIS ANSWER AND NOTHING PLEASE SOMEONE HELP ME NO LINKSS!! Find the midpoint of the segment below and enter its coordinates as an
ordered pair. If necessary, express coordinates as fractions, using the slash
mark for the fraction bar
(-8,-7) (-7,-8)

Answers

Answer:

midpoint is (-15/2, -15/2)

Step-by-step explanation:

Finding the coordinates of the midpoint is easy. All you have to do is find the average of the x-coordinates and the average of the y-coordinates of the endpoints of the segment.

So, in your case

(-8 - 7)/2 = -15/2 is the x-coordinate

(-7 - 8)/2 = -15/2 is the y-coordinate

Therefore, the midpoint is (-15/2, -15/2)

Answer:

(-7.5, -7.5)

Step-by-step explanation:

Remember that the formula is (x1+x2/2, y1+y2/2)

So, we know that -8 is x1 and -7 is y1. We also know that -7 is x2 and -8 is y2.

Lets plug this into our formula and see what we get.

(-8+-7/2, -7+-8/2)

Now lets find the x in the midpoint.

-8+-7/2 is equal to -15/2. This makes x equal to -7.5.

Now lets find the y in the midpoint.

-7+-8/2 is equal to -15/2 as well. This makes y equal to -7.5.

Now we can tell that the coordinates for midpoint will be:

(-7.5, -7.5)

MISCONCEPTIONS:

Always remember that midpoint is nothing like slope. The mid point is something you can point on a graph, wheareas slope is a function that can be lined on a graph.

The formulas for the two things are different as well. Slope is y/x, where you subtract the ys and xs from each other. In a way, midpoint is the exact opposite, which is adding the xs and ys together.

I hope this helps ;)

A right triangle has an angle measure of 52.4 degrees. What is the value of 'x', the missing angle?

Answers

Answer:

The answer is 37.6 degrees

Step-by-step explanation:

Since a right angle is 90 degrees in total, to find the missing degree subtract 52.4 from 90 to find the value of x.

90-52.4= 37.6 degrees

37.6 degrees is your answer

Then answer the multiple-choice questions that follow.From Self-Made Men by Frederick Douglass6 Our best and most valued acquisitions have been obtained either from our contemporaries or from those who have preceded us in the field of thought and discovery. We have all either begged, borrowed or stolen. We have reaped where others have sown, and that which others have strown, we have gathered. It must in truth be said, though it may not accord well with self-conscious individuality and self-conceit, that no possible native force of character, and no depth of wealth and originality, can lift a man into absolute independence of his fellowmen, and no generation of men can be independent of the preceding generation. The brotherhood and inter-dependence of mankind are guarded and defended at all points. I believe in individuality, but individuals are, to the mass, like waves to the ocean. The highest order of genius is as dependent as is the lowest. It, like the loftiest waves of the sea, derives its power and greatness from the grandeur and vastness of the ocean of which it forms a part. We differ as the waves, but are one as the sea. To do something well does not necessarily imply the ability to do everything else equally well. If you can do in one direction that which I cannot do, I may in another direction, be able to do that which you cannot do. Thus the balance of power is kept comparatively even, and a self-acting brotherhood and inter-dependence is maintained.7 Nevertheless, the title of my lecture is eminently descriptive of a class and is, moreover, a fit and convenient one for my purpose, in illustrating the idea which I have in view. In the order of discussion I shall adopt the style of an old-fashioned preacher and have a "firstly," a "secondly," a "thirdly," a "fourthly" and, possibly, a "conclusion."8 My first is, "Who are self-made men?" My second is, "What is the true theory of their success?" My third is, "The advantages which self-made men derive from the manners and institutions of their surroundings," and my fourth is, "The grounds of the criticism to which they are, as a class, especially exposed." Which sentence from the excerpt best expresses the authors message in this part of the text?A. We have all either begged, borrowed or stolen.B. I believe in individuality, but individuals are, to the mass, like waves to the ocean.C. In the order of discussion I shall adopt the style of an old-fashioned preacher and have firstly, a secondly, a thirdly, a fourthly and, possibly, a conclusion.D. My first is, "Who are self-made men?" My second is, "What is the true theory of their success?
