Find The Measure Of Angle A.A) 71C) 349E) 440B) 36D) 1230

Answers

Answer 1

Answer:

The choice C) 34°

Step-by-step explanation:

[tex]75 + (x + 42) + (x + 79) = 180 \\ 2x + 196 = 180 \\ 2x = 180 - 196 \\ 2x = - 16 \\ \\ x = \frac{ - 16}{2} \\ \\ x = - 8 \\ \\ x + 42 = > - 8 + 42 = 34[/tex]

Karen's music library contains 18 fewer playlists than Clarann's music library. The total number of playlists on both music libraries is 40. Find the number of playlists on each person's music library.

Answers

Answer:

let Karen's music library be represented by K

let Clarann's music library be represented by C

C = K +18

C +K =40

put C = K +18 into (C +K =40)

K + 18 +K =40

2K +18 = 40

collect like terms

2K =40 -18

2K =22

divide both sides by 2

K =11

since C = K+18

C= 11 +18

C =29

Karen's music library contains 11 playlists while Clarann's music library contains 29 playlists

Answer:

Out of State = 54

Step-by-step explanation:

Out of State

2/9 = x/243

= 54

Answer:

54

Step-by-step explanation:

7 in-state to 2 out-of-state

The sum of 7 and 2 is 9.

For every 9 students, 2 are out of state.

This is the proportion:

2 out-of-state is to 9 total as x out-of-state is to 243 total

2/9 = x/243

9x = 2 * 243

x = 54

Find the equation (in terms of x) of the line through the points (-2,3) and (4,-9)
y =

Answers

Answer:

y =5

Step-by-step explanation:

m=

−9−7

5−5

=

−16

0

=0

y=mx+b

5=(0)(7)+b

b=5

therefore y = 5

Answer:  y = -2x - 1

Step-by-step explanation:

We can calculate the slope from the two given points.  Slope is the change in y per the change in x, sometimes called the rise (y) over the run (x)

Rise is (-9 -3) = -12

Run is (4 - (-2)) = 6

Slope = Rise/Run = -12/6 = -2

The line is y = -2x + b

Find b by using either of the two known points (solutions).  I'll choose (-2,3) [because I like smaller numbers]

y = -2x + b

3 = -2*(-2) + b

b = -1  [That was only slightly easier than -9 = -2*(4) + b; b = -1]

The equation is y = -2x - 1

Flights 204 and 317 are both approaching Hartsfield Atlanta International Airport from directions directly opposite one another and at an altitude of 2.5 miles. The pilot on flight 204 reports an angle of depression of 17 degrees 47 minutes to the tower, and the pilot on flight 317 reports an angle of depression of 12 degrees 39 minutes to the tower. Calculate the distance between the planes.

Answers

Answer:

19.26 miles

Step-by-step explanation:

Refer to attached picture. Not to scale.

The picture explains all the given parameters.

We need to find the distance d, which is the sum of x and y.

First convert minutes to degrees:

47 min = 47/90 deg = 0.52 deg39 min = 39/90 deg = 0.43 deg

Find x:

x/2.5 = cot (17.52°) ⇒ x = 2.5*3.1677 ≈ 7.92 mi

Find y:

y/25 = cot (12.43°) ⇒ y = 2.5*4.5369 ≈ 11.34 mi

The distance between the planes:

7.92 + 11.34 = 19.26 mi

40°

Answers

50°

Step-by-step explanation:

40° + 90° + ? = 180°

130° + ? = 180°

? = 180° - 130°

? = 50°

Answer: 50 degrees

Step-by-step explanation: The interior angles add up to 180.

1. 40 + 90 + ? = 180

     130 + ? = 180

   -130         - 130

What is the value of x in the equation 3x/4=24

Answers

Answer:

X= 32

Step-by-step explanation:

Answer:

X = 32

Step-by-step explanation:

If you do 24 x 4 you will get 96.

From there you have to divide 3 by 96, since 3 times x has to equal to 96. Since 24 x 4 is 96 and you need to divide 3x by 4.

After you do 96/3 you will get 32. Thus the answer being 32.
