M<A=9x-7,m<B=7x-9,m<C=28-2x

Answer:

  c, b, a

Step-by-step explanation:

The sum of the three angles is 180, so we have ...

  (9x -7) +(7x -9) +(28 -2x) = 180

  14x +12 = 180 . . . . . . simplify

  14x = 168 . . . . . . . . . . subtract 12

  x = 12 . . . . . . . . . . . . . divide by 14

Now, we can find the values of the angles.

  A = 9·12 -7 = 101

  B = 7·12 -9 = 75

  C = 28 -2·12 = 4

The side lengths are in the same order as the angle measures. Shortest to longest, they are ...

  c, b, a

What is the measure of the arc from A to B that does not pass through C?
sergeinik [125]

Applying the inscribed angle theorem, the measure of the arc from A to B is: 100 degrees.

<h3>What is the Inscribed Angle Theorem?</h3>

The inscribed angle theorem states that an inscribed angle in a circle is half the central angle.

Angle BAC = 40 degrees, so, central angle = 80 degrees. Arc BC would also be 80 degrees.

Measure of arc AC through point B = 180 degrees.

Arc AB = 180 - 80 = 100 degrees.

Please help thank you so so so much <br><br> there is more than one answer
Luden [163]

Answer:

B and C work. A and D do not.

Step-by-step explanation:

This is one of those questions that you have to go through each answer to see what the results are. You don't have to go far to eliminate A and D so let's do that first.

A]

5n + 6

Let n = 1

5(1) + 6

5 + 6= 11

However there is trouble beginning with n = 2

5*2 + 6

10 + 6

16     All you need is one wrong answer and the choice is toast. So A won't work.

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

Try D

6(n - 1)+ 5

n=0

6*(-1) + 5

-6 + 5

- 1

And D has been eliminated with just 1 attempt. n= 2 or n = 1 would be even worse.  D is not one of the answers.

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

B

Let n = 1

6(1) + 5

6 + 5

11 The first term works.

n = 2

6*(2) + 5

12 + 5

17 and n = 2 works as well. Just in case it is hard to believe, let's try n = 3 because so far, everything is fine.

n = 3

6*(3) + 5

18 + 5

23 And this also works. I'll let you deal with n = 4

========

C

n = 0

6(0 + 1) + 5

6*1 + 5

6 + 5

11

n = 1

6(1 + 1) + 5

6*2 + 5

12 + 5

17 which works.

So C is an answer.

That's the question ?? ​
Oksanka [162]

Step-by-step explanation:

Before we answer, the area of a Circle given it radius is

a = \pi r {}^{2}

The area of a circle given it diameter is

a =  \pi( \frac{d}{2} ) {}^{2}

So let answers question 1-4.

1. The area is

1024\pi

2. The area is

576\pi

3.

1.225\pi

4.

309.76\pi

For the 5th problem, circumference is

\pi \times d

where d is the diameter and

2\pi  r

where r is the radius.

A circumference of 100 m means the radius is 50 because

2\pi \times r = 100\pi

r = 50

So this means the area is

2500 {\pi}
