Step-by-step explanation:

m<FDE = 45° (alternate angles)

w = 70° (corresponding angles)

x = 42° (atlernate angles)

x + z = 180° (linear pairs)

or, z = 180° - 42°

so, z = 138°

Solve for X round to the nearest tenth of a degree if necessary

Answers

Answer:

x ≈ 54.2°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{WV}{VW}[/tex] = [tex]\frac{50}{36}[/tex] , then

x = [tex]tan^{-1}[/tex] ( [tex]\frac{50}{36}[/tex] ) ≈ 54.2° ( to the nearest tenth )

The number of messages posted each day on an online message board during the first 5 days it was open are listed below

2,350 2,900 3,450 4,000 4,550

The number of messages posted each day follows a pattern. Which expression can be used to determine the number of messages

posted on the nth day?

O A. 2,350n

ов.

550(n + 1,800)

O C.

550n + 1,800

O D.

1,800n + 550

Answers

= C, 550n + 1800

Here is how you make a expression for a sequence:

1) Firstly, identify the number gap. This is 550. 2350 + 550 = 2900. 2900 + 550 = 3450, ect. So this means that it is 550n.

2) n is basically just the number in the sequence it stands on. n for 2350 is 1. So now you need to know what you must add to 550n to get whatever n is. We will choose 2350. n is 1 for it. 550 x 1 = 550. 2350 - 550 = 1800. So it is 550n + 1800.

Answers:Reason 1: GivenReason 2: Vertical AnglesReason 3: SAS Similarity Theorem

==============================================

Further Explanation:

Whenever you are doing a proof, always start with the given info. It may seem silly to literally repeat (word-for-word) what your teacher has given you, but this is how all proofs start out. It helps place an anchor point in which you can connect to what you want to prove.

So this is why the first line is literally a repeat of what your teacher has stated. The reason you'll state is "given".

------------------

For reason 2, we use the vertical angle theorem. Vertical angles are always congruent.

Vertical angles form whenever we have an X shape like this of two segments crossing. The angles are opposite one another (almost like mirror images of sorts).

-----------------

Lastly, reason 3 uses the SAS (side angle side) similarity theorem.

This is the theorem which says that if you have two pairs of sides in proportion and a pair of congruent angles between those sides, then we can prove the triangles similar.

Statement 1 handles the sides being in proportion. Statement 2 handles the congruent angles.

As you can see, everything in this proof builds step by step toward the final goal of saying triangle ABC is similar to triangle EBD.

Which sequence is geometric and which is arithmetic?

Answers

Answer:

See below

Step-by-step explanation:

Geometric sequences have a common ratio while arithmetic sequences have a common difference.

On the left table, we can see that it's an arithmetic sequence because 3+2=5, 5+2=7, and so on.

On the right table, we can see that it's a geometric sequence because 3*2=6, 6*2=12, and so on.

Basically, if you see a multiplication pattern for the output, it's a geometric sequence. If you see an addition (or subtraction) pattern for the output, it's an arithmetic sequence

Explanation: Divide 113.4 by 18 to find x. Prove x by multiplying by 18 to get 113.4.
x=6.3
113.4 = x(18)

Answer:

The answer is B = 113.4 = x (18)

x = 6.3

Step-by-step explanation:

A product of a number, x, and 18 is 113.4.

This means x*18=113.4

Now we solve:

x(18) = 113.4, Also can be written as 113.4 = x(18)

18x = 113.4

/18     /18

x = 6.3

What are the coordinates of the point (-3, 0) after a translation 2 units up?

A. (-3,2)
B. (-5,0)
C. (-3,-2)
D. (-1,0)

Answers

Answer: (-3,2)

Step-by-step explanation:

It's a translation 2 units UP, which means vertically, which means the Y Axis, so your (-3,0) which is formatted like: (x,y) would add 2 to the y variable of the coordinate -> (-3,2), You don't even need a graph for this problem tbh.

The coordinates of the (-3, 0) after a translation 2 units up is: A. (-3, 2).

What is Translation?

Translation is a form of transformation, whereby the points of a figure is moved from one position to another by the same distance in a given direction.

Given a point, (-3, 0), after translation 2 units up, that is, 2 units up along the vertical axis (y-axis), we would have:

(-3, 0 + 2 units) = (-3, 2).

Thus, the coordinates of the (-3, 0) after a translation 2 units up is: A. (-3, 2).

1. Mrs. Chauke is 66 years old. She earns R180 per hour and works eight hours a day from Monday to Friday. Determine Mrs. Chauke's annual income if she earns R32 040 per month.

Answers

Answer:

Matter of deleting not useful facts and using what we know and need.

Mrs.Chau.ke is 66 years old is not useful since this age doesn’t ask for age or the effect of age.

Earns 180 per hour and works 8 hours a day is useless since we’re already given the monthly income.

The monthly income 32040 is the most important here since we need to find the ANNUAL income which means yearly.

32040 per month * 12 months is 384480

384480 is the annual income

Mrs. Chauke's annual income if she earns R32 040 per month is

R384 480​

The given parameters are:

Hourly rate = R180

Work time = 8 hours a day

Monthly income = R32040

There are 12 months in a year.

So, the annual income is:

Annual = 32040 * 12

This gives

Annual = 384480

Hence, Mrs. Chauke's annual income if she earns R32 040 per month is

R384 480​
