Answer:

sin(D) = cos(F)

cos(D) = sin(F)

tan(D) = 1/tan(F) which means tan(F) = 1/tan(D)

Step-by-step explanation:

First it is important to know that the sine of an angle is the fraction of the opposite side over the hypotenuse side, while cosine is the adjacent over the hypotenuse and finally tangent is opposite over adjacent.  You can't take the sine, cosine or tangent of the right angle like this though.  

sine is o/h

cosine is a/h

tangent is o/a

So let's do each angle.

Keep in mind E is the right angle so we can't take any trig function of it with SOH CAH TOA so let's do D first.

D has an adjacent side of f since e is the hypotenuse, which leaves d as the opposite  so lets go throught he trig functions.

sin(D) = d/e

cos(D) = f/e

tan(D) = d/f

Now let's do the same with F.  d is adjacent, e is the hypotenuse and f is opposite.

sin(F) = f/e

cos(F) = d/e

tam(F) = f/d

Now, you can actually match them up

sin(D) = cos(F)

cos(D) = sin(F)

tan(D) = 1/tan(F) which means tan(F) = 1/tan(D)

And just looking at that we've answered the question.    let me know if that doesn't make

Suppose R = {1,3,5,7,9,11,13,15,17} and D={3,6,9,12,15,18,21,24,27} r d
Free_Kalibri [48]

The intersection of sets R and D is give by the following set:

R ∩ D = {3, 9, 15}.

<h3>What is the missing information?</h3>

This problem is incomplete, but researching it on a search engine, we find that it asks the intersection of sets R and D.

<h3>What is the set that is the intersection of two sets?</h3>

The set that is the intersection of two sets is composed by the elements that belong to both sets.

For this problem, the sets are given as follows:

  • R = {1,3,5,7,9,11,13,15,17}.
  • D={3,6,9,12,15,18,21,24,27}

Hence the intersection is given by:

R ∩ D = {3, 9, 15}.

As the elements 3, 9 and 15 are the only ones that belong to both sets.

Find the area of a rectangle that is 16 3/5in. by 8 9/10
Alenkinab [10]
<h2>Greetings!</h2>

Answer:

Area is 147.74

Step-by-step explanation:

You need to recall that the equation for the area of a rectangle is:

Length * Width = area

So 16 3/5 * 8 9/10 = area

Rearrange so the whole numbers are being multiplied and the fractions are too:

We need to make the denominator same, this can be done by simply multiplying 3/5 by 2:

3/5 * 2 = 6/10

Now the two numbers can be written as 16.6 and 8.9.

Multiply both numbers by 10:

166 * 89 = 14774

Then divide this by 100 (two lots of division by 10)

14774 ÷ 1000 = 147.74

So the area of the rectangle is 147.74!

Explain how you know 7/12 is greater than 1/3 but less than 2/3
Roman55 [17]
7/12
1/3=4/12
2/3=8/12

7/12>1/3
<span>7/12<2/3
</span>

convert all of these to a common denominator:
7/12 , 1/3 , 2/3
---
7/12 = 7/12
1/3 = 4/12
2/3 = 8/12
---
place into compound inequality:
---
(1/3=4/12) < (7/12=7/12) < (2/3=8/12)
