Answer:

To determine the value of X, what you would need to do is to use a trigonometric ratio, that would make use of the value of x and the side length of 12. This can either be, sin 30 or cos 60. Both of them will enable you to solve for x.

The final value for x would be either

X = 12/Sin 30

X = 12/Cos 60

Compute these in your calculator and you will find the final value in these cases.

Answer:

160.00° Degrees

Step-by-step explanation:

To find the answer, we have to use the interior angle formula which is

(n-2)*180, where n is the number of sides. This formula gives us the sum of all interior angles in a polygon having ‘n’ sides.

For a polygon with 18 equal sides, first finding the sum of all interior angles of the polygon:-

=(n-2)*180= (18–2)*180=16*180=2880 degree.

We found the sum of all interior angles of 18 sided polygon and it is 2880 degrees.

The polygon we are considering has all sides equal, which means it is a regular polygon. So we can conclude that all of its interior angles are equal.

Sum of all eighteen angles=2880, One angle=2880/18=160 degrees.

Thus, we concluded that the interior angle of the regular eighteen sided polygon

is 160 degrees

Answer:

You're wrong, it's the bottom left

Step-by-step explanation:

x^2-49 is a difference of squares so it factors into (x+7)(x-7) which obviously cancels out with the denominator leaving x-7 left. This is the line you should graph, but keep in that x+7 is still in the denominator so x cannot be equal to -7 which means that this point should be be on the line which leaves the answer to be the one on the bottom left.

Step-by-step explanation:

Answer:

1) x = 41.8 deg

2) x = 64.2 deg

3) x = 51.3 deg

Step-by-step explanation:

Problem 1

For angle x, 4 is the opposite leg and 6 is the hypotenuse.

sin x = 4/6

x = sin^-1 2/3

x = 41.8 deg

Problem 2

For angle x, 14 is the adjacent leg, and 29 is the opposite leg.

tan x = 29/14

x = tan^-1 29/14

x = 64.2 deg

Problem 3

For angle xm 25 is the adjacent leg, and 40 is the hypotenuse.

cos x = 25/40

x = cos^-1 5/8

x = 51.3 deg

Answer:

-18x

Step-by-step explanation:

First step: remove the parentheses.

So, you'll have -3x*6.

multiply the numbers (3 x 6 = 18)

and you'll get -18x.

hope this helps!

Answer:

Step-by-step explanation:=(1+sinA)2+cos2A/cosA(1+sinA)

=1+sin2 A+2sin A+cos2 A/cos A(1+sin A)

=1+2sin A+1/cos A(1+sin A)

=2(1+sin A)/cos A(1+ sin A)

=2sec A

Answer:

see explanation

Step-by-step explanation:

Consider the left side

[tex]\frac{1+sinA}{cosA}[/tex] + [tex]\frac{cosA}{1+sinA}[/tex] ← combine into a single fraction

= [tex]\frac{(1+sinA)^2+cos^2A}{cosA(1+sinA)}[/tex] ← expand and simplify numerator

= [tex]\frac{1+2sinA+sin^2A+cos^2A}{cosA(1+sinA)}[/tex] [ sin²A + cos²A = 1 ]

= [tex]\frac{1+2sinA+1}{cosA(1+sinA)}[/tex]

= [tex]\frac{2+2sinA}{cosA(1+sinA)}[/tex] ← factor out 2 on the numerator

= [tex]\frac{2(1+sinA)}{cosA(1+sinA)}[/tex] ← cancel (1 + sinA) on numerator/ denominator

= [tex]\frac{2}{cosA}[/tex]

= 2secA = right side, thus verified

Answer:

105 students and 150 guests

Step-by-step explanation:

equation to find the answer are

1x + 5y = 855

x + y = 255

with

x + y = 255

x = 255 - y

now we replace x with (255 - y) into 1x + 5y = 855 to find y

1(255 - y) + 5y = 855

255 - y + 5y = 855

255 + 4y = 855

4y = 855 - 255

4y = 600

y = 150 (number of guests)

now we got y = 150, let's find x

x + y = 255

x + 150 = 255

x = 255 - 150

x = 105 (number of students)

Answer:

1  hour and 12 minutes

Step-by-step explanation:

Let's say x = time it takes for the trains to be 204 miles apart.

Speed = Distance/Time,

Time = Distance/Speed,

x = 204/ (80 + 90) = 204/170 = 1 and 1/5 hours or 1  hour and 12 minutes

Step-by-step explanation:

Answer:

1 1/2

Step-by-step explanation:

1.) First find the common denominator of the 2 fractions (8)    4: 4

    8: 4, 8

2.) then you write a new expression with the numerator left blank and the denominator as 8 shown below in the step by step explanation.  /8 + /8

3.)3/8 + 2/4 multiply by 1 both numerator and denominator for the first fraction. And multiply by 2 both numerator and denominator for the second fraction. 3/8 + 4/8.

4.) Then you add those 2 fractions which I assume you already know how by adding the numerators together, and get 12/8.

5.) You simplify 12/8 and get 1 4/8. 4/8 is equal to 1/2 so its 1 1/2.

Answer for x is 5

Step by step explanation:

Answer:

The points lie in

✔ the same quadrant

The distance is

✔ 4 units

Step-by-step explanation:

the same quadrant

4 units

The  distance between the two points (1, 2) and (5, 2) is 4 units. And both the points (1, 2) and (5, 2) lie in the same quadrant.

Distance between two points is the length of the line segment that connects two given points.

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

According to the given question

We have

Two points

(1, 2) and (5, 2)

Let,

[tex](x_{1},y_{1}) = (1, 2)[/tex]

And, [tex](x_{2},y_{2} ) = (5,2)[/tex]

Therefore,

The distance between the points (1,2) and (5, 2)

= [tex]\sqrt{(5-1)^{2} +(2-2)^{2} }[/tex]

[tex]=\sqrt{(4)^{2}+0 }[/tex]

[tex]=4[/tex] unit.

Hence, the  distance between the two points (1, 2) and (5, 2) is 4 units.

Since, the x coordinate and y coordinate of both the points (1,2) and (5, 2) are positive. Therefore, they both lie in the first quadrant. Hence, the points lie in the same quadrant.

Answer:

answer C: 140 cm

Step-by-step explanation:

If the water rises 14cm in 2 seconds, 21cm in 3 seconds etc... Then the water rises at 7cm per second. Multiply this by 20 seconds and you get 140cm

By find how high the water would be after 20 seconds, you would find out much height is increasing each second.

21 - 4 = 7

28 - 21 = 7

35 - 35 = 7, and so forth.

So, we know that 7 cm is increasing each second. You would just add 7 to the height for each second.

2 --> 14

3 --> 21

4 --> 28

5 --> 35

6 --> 42

7 --> 49

8 --> 56

9 --> 63

10 --> 70

11 --> 77

12 --> 84

13 --> 91

14 --> 98

15 --> 105

16 --> 112

17 --> 119

18 --> 126

19 --> 133

20 --> 140

Thus, after 20 seconds, the water's height would be c) 140 cm.
