The angle between the lines of sight to the airplane at c and Jenny's airplane to the nearest tenth of a degree is 25.1°.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

From the figure,

Cosine theorem:

Cos 120° = (4.2² + 5.7² - BC²) / (2 x 4.2 x 5.7)

-0.5 = (17.64 + 32.49 - BC²) / 47.88

-23.94 = 50.13 - BC²

BC² = 50.13 + 23.94

BC = √(74.07)

BC = 8.6

Sine theorem:

BC / Sin ∠A = AC / Sin ∠B

8.6 / Sin ∠A = 4.2 / Sin ∠B

8.6 / 120 = 4.2 / Sin ∠B

Sin ∠B = (4.2 x 120) / 8.6

Sin ∠B = 58.60

∠B = 25.1°

Thus,

The angle is 25.1°.

Answer:

5/12

Step-by-step explanation:

Total pound of oranges = 5

Number of piles = 12

Weight of the oranges in each pile = Total pound of oranges / Number of piles

= 5 / 12

The rational number which represents the weight of the oranges in each pile is 5/12

1) 13.57

+2.93

With this, we subtract from the back Meaning we add starting from back to forward;

13.57

+2.93

16.50

We have that because when you add 7 and 3 you get 10 so we write the 0 there and add the remaining 1 to the 5 making it 6 and then 6 plus 9 will give you 15 then we write the 5 then we add the remaining 1 to the 3 making it 4 then we add the 4 to the 2 making it 6 after this there is no remainder so we just write the 1.

Step-by-step explanation:

Answer:

n = number of nickels = 7

d = number of dimes = 10

p = number of pennies = 20

Step-by-step explanation:

Let

n = number of nickels

d = number of dimes

p = number of pennies.

n + d + p = 37

0.05n + 0.10d + 0.01p = 1.55

p = 2d

Substitute p = 2d into the equation

n + d + 2d = 37

0.05n + 0.10d + 0.01(2d) = 1.55

n + 3d = 37

0.05n + 0.10d + 0.02d = 1.55

n + 3d = 37 (1)

0.05n + 0.12d = 1.55 (2)

Multiply (1) by 0.05

0.05n + 0.15d = 1.85

0.05n + 0.12p = 1.55

Subtract

0.15d - 0.12d = 1.85 - 1.55

0.03d = 0.3

d = 0.3/0.03

= 10

d = 10

p = 2d

= 2(10)

p = 20

n + d + p = 37

n + 10 + 20 = 37

n + 30 = 37

n = 37 - 30

n = 7

n = number of nickels = 7

d = number of dimes = 10

p = number of pennies = 20

The constant of proportionality is 40 sour patch kids per day

Step-by-step explanation:

Here, we want to find the constant of proportionality

From the question, we are told that he eats 20 sour patch kids in half a day

what this mean is that he will eat 20 * 2 = 40 sour patch kids in a day

The constant of proportionality is thus 40 sour patch kids per day

Answer: (3,1)

Step-by-step explanation:

2x + 3y = 9

(x + 5y = 8) -2

2x + 3y = 9

-2x - 10y = -16

      -7y = -7

         y = 1

2x + 3(1) = 9

       2x = 6

        x = 3

Answer:

5.8516

Step-by-step explanation:

To find the distance between these 2 points we have to use the distance formula. The distance formula is as follows:

[tex]d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}[/tex]

Let's find the variables of this equation:

x2 = 6

x1 = 1

y2 = 4

y1 = 2

Now, we can plug these in to the equation:

[tex]d = \sqrt{(6-1)^2 + (4-2)^2}[/tex]

Next, let's solve:

[tex]d = \sqrt{(5)^2 + (2)^2}\\d = \sqrt{25 + 4} \\d = \sqrt{29} \\d = 5.8516[/tex]

Therefore, the distance between points (1,2) and (6,4) is 5.8516

Answer: $2

Step-by-step explanation: 20 percent of 10 is 2

Hope I did this right

The selling cost of the mug is the amount of $12.

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Misha obtained a score of 57% on her exam, that corresponds to 67 out of 100.

We have been given that Aden spent $10 on a mug and then sold it, making a 20% profit.

The original cost of the mug is $10.

The selling cost of the mug = original cost + 20% of the original cost

The selling cost of the mug = $10 + 20% of $10

The selling cost of the mug = 10 + (20/100)10

The selling cost of the mug = 10 + 0.20 × 10

The selling cost of the mug = 10 + 2

The selling cost of the mug = $12

Therefore, the selling cost of the mug is the amount of $12.

Answer:

It would most likely be in the 100's so maybe 105

Answer:

When s = 20, r = 9

Step-by-step explanation:

Given,

s is directly proportional to (r + 1)

s = k(r + 1)

(k is the constant of proportionality)

When s = 8,

8 = k(3 + 1)

8 = k(4)

8 = 4k

8/4 = k

2 = k

When s = 20,

20 = 2(r + 1)

20 = 2r + 2

20 - 2 = 2r

18 = 2r

18/2 = r

9 = r

Answer:

The three integers are

11, 13, and 15.

Step-by-step explanation:

. The sum of these is 39, so we can write:

x+(x+2)+(x+4)=39

Open the brackets and simplify.

x+x+2+x=+4=39

3x+6=39

Subtract 6 from each side.

3x=33

Divide both sides by 3.

x=11

Therefore: (x+2)=13 and (x+4)=15

Answer: ∠A = 70°

because ABC is an  isosceles triangle and AB =  AC
