The angle between the two tangents drawn from an external point to a circle and the angle subtended by the line segment joining the points of the contact at the Centre are supplymentary,

So,

Answer:

15) 125°

16 100°

Step-by-step explanation:

The short arc where two tangents intersect a circle, and the angle where the tangents meet are supplementary.

15) ? = 180° -55° = 125°

16) ? = 180° - 80° = 100°

_____

Additional comment

The quadrilateral formed by the tangents and the radii to the points of tangency has a total interior angle measure of 360°. The angles where the radii meet the tangents are 90°, so the sum of the external angle and the central angle is 360° -90° -90° = 180°. That is, the external angle and the central angle are supplementary.

Help me pls I don't know what to do

Answers

Formula- Area = L • W

So...

Length = 18 + 3

Width = 18 + 3

Since you’re adding 18 + 3 for Length AND Width, you’re going to get a sum of 21 for each.

Length = 21

Width = 21

Now you’re gonna want to multiply 21 by itself.

21 • 21 = 21 + 420 = ?

Which leaves you with the final sum of...

Area = 441 yds.

Find the sum of the angle measures in a regular polygon.

A) 720*

B) 900*

C) 1080*

D) 1260*

Please help!! Thanks

Answers

Answer:

D) 1260°

Step-by-step explanation:

In an n-sided polygon, the sum of all angles is equal to (n-2)*180°.

Look at it this way - let's add a point in the middle and connect it to each vertex. Then we've got n triangles for a total of n*180°, but all of the angles at the middle point aren't "part" of the polygon, so a full 360° angle should be subtracted, giving us n*180°-360° = (n-2)*180°

You can easily confirm that it works for triangles and quadrangles ;)

The figure in the picture has 9 sides, so the sum of angles is (9-2)*180° = 7*180° = 1260°

1260°

The sum of the fifth and sixth term of an AP is 30.If the third term is 5.Find the first term.

Answers

Answer:

The first term is -3.

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between two consecutive terms is always the same, and it is called common difference d.

The nth term is given by:

[tex]a_n = a_1 + (n-1)d[/tex]

In which [tex]a_1[/tex] is the first term.

If we have the mth term instead of the first, we have:

[tex]a_n = a_m + (n-m)d[/tex]

We have the third term, and need the fifth and the sixth:

So we write both the fifth and the sixth in function of the third, then:

[tex]a_5 = a_3 + 2d = 5 + 2d[/tex]

[tex]a_6 = a_3 + 3d = 5 + 3d[/tex]

The sum of the fifth and sixth term of an AP is 30

We use this to find [tex]d[/tex]. So

[tex]a_5 + a_6 = 30[/tex]

[tex]5 + 2d + 5 + 3d = 30[/tex]

[tex]5d + 10 = 30[/tex]

[tex]5d = 20[/tex]

[tex]d = \frac{20}{5} = 4[/tex]

First term:

The third term is:

[tex]a_3 = a_1 + 2d[/tex]

Since [tex]a_3 = 5, d = 4[/tex]

[tex]a_1 = a_3 - 2d = 5 - 8 = -3[/tex]

The first term is -3.

A bag contains 20 slips of paper Individually numbered. If a slip of paper and a letter in the word PENNSYLVANIA is chosen at randomfind each probability.

Answers

Answer:

[tex]P(M4\ n\ V) = 2.083\%[/tex]

Step-by-step explanation:

Given

Paper = 20 slips

Word: PENNSYLVANIA

Required

Determine P(Multiple of 4 and V)

The sample size of the 20 slips is:

[tex]n(S) = 20[/tex]

The outcomes of multiples of 4 is:

[tex]M4= \{4,8,12,16,20\}[/tex]

[tex]n(M4) = 5[/tex]

So, the probability of multiples of 4 is:

[tex]Pr(M4) = \frac{5}{20}[/tex]

[tex]Pr(M4) = \frac{1}{4}[/tex]

The sample size of PENNSYLVANIA is:

[tex]n(S) = 12[/tex]

The outcome of V is:

[tex]n(V) = 1[/tex]

So, the probability of V is:

[tex]P(V) = \frac{1}{12}[/tex]

So, the required probability is: P(Multiple of 4 and V)

[tex]P(M4\ n\ V) = P(M4) * P(V)[/tex]

[tex]P(M4\ n\ V) = \frac{1}{4} * \frac{1}{12}[/tex]

[tex]P(M4\ n\ V) = \frac{1}{48}[/tex]

[tex]P(M4\ n\ V) = 0.02083[/tex]

Express as percentage

[tex]P(M4\ n\ V) = 0.02083 * 100\%[/tex]

[tex]P(M4\ n\ V) = 2.083\%[/tex]

2 3/6 boxes and 1 2/3 boxes were recycled what is the total

Answers

Since you are recycling the boxes you will be subtracting 2 3/6 and 1 2/3 since you’re a denominators you’re not mad she have to find a common denominator which would be six. So you have to do 2/2 x 2/3 = 4/6. So then you would do 3/6 - 4/6 = 1/6. Then you would subtract 1-2=1. Then you would do 1 + 1/6 = 1 1/6

So the answer is 1 1/6.

What is an Equation?

An equation is used to show the relationship between two or more variables and numbers.

It would take Shandra 40 minutes (2/3 hours) to sand a table while it would take kelly 1 hour.

Let t be the time it would take to sand the table working together. Hence:

(1/(2/3) + 1/1)t = 1

(3/2 + 1)t = 1

2.5t = 1

t = 0.4 hours = 24 minutes

It would take 24 minutes to sand the table working together.
