The exact value of cos [tex]\theta[/tex] is 21/29.

One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.

We have, point (21, 20)

So, Adjacent side= 21 and opposite side= 20

Using Pythagoras theorem

H= √ 21²  + 20²

H= √441 + 400

H= √841

H= 29 unit

So, the trigonometric ratio

cos [tex]\theta[/tex] = Adjacent side/ H

cos [tex]\theta[/tex] = 21/29

Thus, the exact value of cos [tex]\theta[/tex] is 21/29.

they are equal so what one shows that they rise 2 run 2

Step-by-step explanation:

The correct option is Option A: The system of inequalities that are shown within the graph are in y < x and y > 2.

Inequality means the relation that creates a non-equal comparison between two numbers or other expressions. It is the condition of unequalness. A system of inequalities is a set of two or more inequalities in one or more than one variables.

According to the question,

For the given condition,

The graph basically shows the inequality relationship between x and y.

The correct system of inequality is found by plotting all the choices within the graph.

The graph below shows the system of inequalities as shown for the expression,

Therefore, the system of inequalities that are shown within the graph is in option (a) i.e y < x and y > 2.

Answer:

Many solutions

Step-by-step explanation:

First, you distribute the 6 into the parenthesis:

4x+6=6(x+1)-2x

4x+6=6x+6-2x

4x+6=4x+6

subtract 6 from both sides

4x=4x

All real numbers can be the solution

Step-by-step explanation:

Answer:

(2, -8)

Step-by-step explanation:

The answer is (2, -8) because when you reflect a point across the x-axis, the x-coordinate always remains the same, but the y-coordinate will change. In other words, the y-coordinate becomes the opposite (signs change). In this case, since the y-coordinate was positive 8, when you reflect the point across the x-axis, the y-coordinate will change to -8

Answer:

A. Chocolate Only = 17

B. Mango only = 1

C.Strawberry Only = 5

D.Chocolate and strawberry = 4

E.None of the flavors​ = 9

Step-by-step explanation:

Kindly check attached picture for detailed explanation

A set is a group of related item.

Let:

[tex]C \to Chocolate[/tex]

[tex]M \to Mango[/tex]

[tex]S \to Strawberry[/tex]

So, we have:

[tex]C = 28[/tex]

[tex]M = 15[/tex]

[tex]S = 20[/tex]

[tex]n(C\ n\ S) = 8[/tex]

[tex]n(M\ n\ S) = 11[/tex]

[tex]n(C\ n\ M) = 7[/tex]

[tex]All = 4[/tex]

[tex]n(U) = 50[/tex] -- the population

(a) Chocolate only.

This is calculated as:

[tex]C\ only = C - n(C\ n\ S) - n(C\ n\ M) + All[/tex]

So, we have:

[tex]C\ only = 28 - 8 - 7 + 4[/tex]

[tex]C\ only = 17[/tex]

(b) Mango Only

This is calculated as:

[tex]M\ only = M - n(M\ n\ S) - n(C\ n\ M) + All[/tex]

So, we have:

[tex]M\ only = 15 - 11 - 7 + 4[/tex]

[tex]M\ only = 1[/tex]

(c) Strawberry only

This is calculated as:

[tex]S\ only = S - n(M\ n\ S) - n(C\ n\ S) + All[/tex]

So, we have:

[tex]S\ only = 20 - 11 - 8 + 4[/tex]

[tex]S\ only = 5[/tex]

(d) Chocolate and strawberry

This has already been given as:

[tex]n(C\ n\ S)\ only=n(C\ n\ S) - All[/tex]

[tex]n(C\ n\ S)\ only=8 - 4[/tex]

[tex]n(C\ n\ S)\ only = 4[/tex]

(e) None

See attachment for the Venn diagram that represents the set

Subtract the sum of all the numbers in the Venn diagram from the total (50)

[tex]None = 50 - (17 + 1 + 5 + 4 + 4 + 7 + 3)[/tex]

[tex]None = 9[/tex]

Answer:

x° = 123

Step-by-step explanation:

this triangle is isoceles so it has 2 congruent angles.

let y be the second angle

the sum of a triangle's angle is 180°

[tex]180 = 66 + y + y \\180 = 66 + 2y[/tex]

add [tex]-66[/tex] to both sides

[tex]180 - 66 = 2y + 66 - 66 \\114 = 2y[/tex]

divide both sides by 2

[tex]\frac{114}{2} = \frac{2y}{2}[/tex]

[tex]57 = y[/tex]

we khow that [tex]x + y = 180[/tex]

[tex]x + y = 180 \\x + 57 = 180[/tex]

add -57 to both sides

[tex]x + 57 - 57 = 180 - 57 \\x = 123[/tex]

Answer:

The endpoint coordinates are (3,12)

Step-by-step explanation:[tex]\frac{5+x^{2} }{2} =4[/tex] [tex]\frac{-6+y^{2} }{2} = 3[/tex]

You multiply 4 by 2 which gives you 8 and write the equation[tex]5+x^{2} =8[/tex] then you subtract 5 from 8 to get 3 for the x coordinate.

You multiply 3 by 2 which gives 6 and writhe the equation[tex]-6+y^{2}=6[/tex] then you substitute the -6 for +6 and add +6 and 6 to get 12 for the y coordinate.

To check use the midpoint formula with coordinates D and your endpoint coordinates[tex]\frac{5+3}{2}=\frac{8}{2} =4 \\[/tex]  [tex]\frac{-6+12}{2} =\frac{6}{2} =3[/tex] and you get the answer for the midpoint which is (4,3)

Answer:

y = x + 14

Step-by-step explanation:

given

5x−5y=−2, we'll rearrange this into slope - intercept form

5x + 2 = 5y

5y = 5x + 2    (divide both sides by 5)

y = x + (2/5)

recall that the general equation of the slope-intercept form of a linear equation:

y = mx + b, the value of m represents the slope of the line

in our case, comparing the above equations, it is clear that the slope m = 1.

We are given that our line is parallel to the above line, hence it will also have  a slope of 1.

if we substitute m = 1 into the general equation, we will get

y = x + b

in order to find the value of b, we will substitute the given point (-10,4) into the equation:

4 = -10 + b   (add 10 to both sides)

b = 4 + 10

b = 14

hence our equation is y = x + 14

Answer:

288

Step-by-step explanation:

24 is a multiple of 12, and 36 is a multiple of 12, so the LCM of 24, 32, and 36 will also be the LCM for 12 and 16.

24 = 2^2 * 3

32 = 2^5

36 = 2^2 * 3^2

LCM = 2^5 * 3^2

LCM = 288
