In a right angled triangle, we can use SOH CAH TOA . 
assuming you are confident with Pythagoras, your first step is to find the hypotenuse(the longest side of the triangle). the second step is to set out your equations( one of the following depending on which sides you have available).
1)singAngle = opposite/hyp 
   locate your angle, the side that it facing it( not touching it directly) will be your opposite. then locate your hyp. enter all values into the equation above. to find the actual value you will need to find the inverse of sine, thus you will (assuming you have a calculator) do shift sin , and on the screen you will see sin^-1 which is the inverse of sin. type in shift sin (opp/hyp) and press equals to get your angle. 
2) Cosineangle= adjacent/hyp 
adjacent side is the side that is touching the angle BUT not the longest side of the triangle( thats the hyp). 
do as above. using shift cos to get cos^-1
3) same as the other two except you use tanangle=opp/adjacent
then shift tan to get tan^-1

Sinα=(opposite side)/hypotenuse

cosα=(adjacent side)/hypotenuse

tanα=(opposite side)/(adjacent side)

In a right triangle the longest side is the hypotenuse.

If one angle opposite a side is α, the angle opposite the other side is 90-α (because the sum of all angles must be 180° for any triangle)

I hope that helps as your question is not really clear, if you have any more specific questions, I'd be happy to help out. :)

Correct Option is D.  Lines 72-75 ("Consider . . . happiness")

In lines 72-75, Wollstonecraft provides evidence that society’s leaders grant freedoms that privilege men. She argues that while society’s leaders believe they “are acting in the manner best calculated to promote [women’s] happiness,” their decisions don’t allow women to “contend for their freedom.”

Choices A, B, and C do not provide the best evidence that society’s leaders grant freedoms that privilege men over women.

<h3>The lines from passage are - </h3>

Consider—I address you as a legislator—

whether, when men contend for their freedom, and

to be allowed to judge for themselves respecting their

own happiness

Previous Question is :

"In Passage 2, the author claims that freedoms granted by society's leaders have:"

<h3>This question is based on paragraph from Mary Wollstonecraft, A Vindication of the Rights of Woman. Originally published in 1792, which is given below -</h3>

Passage 2 -

"Contending for the rights of woman, my main argument is built on this simple principle, that if she be not prepared by education to become the companion of man, she will stop the progress of 45 knowledge and virtue; for truth must be common to all, or it will be inefficacious with respect to its influence on general practice.

Ilia_Sergeevich [38]

Answer:

C.It is a​ one-tailed test since the alternative hypothesis states that the parameter is greater than the hypothesized value.

Step-by-step explanation:

Let p be the percentage of students enrolled in an introductory Chemistry class dropped before the midterm. Then null and alternative hypotheses are:

H_{0}: p=10%

H_{a}: p>10%

The alternative hypothesis states that the parameter is greater than the hypothesized value.

Can someone please help me please I really need help please answer it correctly
kvv77 [185]

Answer:

<h3>Princeton Florist</h3>

Let the total charge is y, the number of small arrangements is x.

<u>Total charge will be:</u>

  • y = 13x + 47
<h3>Chad's Flowers</h3>

<u>Total charge will be:</u>

  • y = 17x + 35

<u>Since the total charge is same in both shops, we have:</u>

  • 13x + 47 = 17x + 35

<u>Solve for x:</u>

  • 17x - 13x = 47 - 35
  • 4x = 12
  • x = 3

<u>Total cost is:</u>

  • 13*3 + 47 = 39 + 47 = 86

<u>Small arrangements</u> = 3, <u>cost </u>= $86
