Answer:

x = 5

Step-by-step explanation:

the angles of a triangle add up to 180°

17x+13x+6x=180

36x = 180

x = 5

Answer: 5

Step-by-step explanation:

To start off, the angles of a triangle add up to 180.

Therefore, you would find he answer by adding all the angles together and making it equal to 180.

13x+17x+6x=180

When you solve the equation, you will get X=5.

To check your work:

13 times 5=65

17 times 5=85

6 times 5=30

65+85+30=180

Answer:

Step-by-step explanation:

You can figure out the angle DBC by the alternate interior theorem. Angle DBC=56 degrees. You already figured out BD.

Since we know BD, BC, and the angle DBC we can use the Law of cosine to find CD

The law of cosine is

CD^2=BC^2+BD^2-2(BC)(BD)cos DBC

Plug in what we know

CD^2=18^2+12.1^2-2(18)(12.1)cos 56

CD^2≈228.8387

Find the square root to isolate CD.

CD≈15.1

Answer:

use points (0,5) and (1,7)

see below for graph

Step-by-step explanation:

First, we'll turn the equation from point slope form (y-y1=m(x-x1)) into slope intercept form (y=mx+b)

y+1=2(x+3)

do the distributive property

y+1=2x+6

subtract 1 from both sides

y=2x+5

We'll need two points to graph the line.

You can subsitute x or y as any number you like and solve the equation.

For example:

if x=0:

y=2(0)+5

y=5

so the point would be (0,5)

and if x=1

y=2(1)+5

y=2+5

y=7

point: (1,7)

Use the points (0,5) and (1,7)

See below if you would like to see how it looks like on a graph.

Hope this helps!

Answer:

10.4m

Step-by-step explanation:

We solve the above question using the Trigonometric function of Tangent.

The formula is given as:

tan θ = Opposite/Adjacent

θ = Angle of Elevation = 46°

Opposite = Height of the tree = x

Adjacent = Distance from the base of the tree = 10m

Hence:

tan 46 = x/10

Cross Multiply

x = tan 46 × 10

x = 10.355303138m

Approximately to the nearest tenth = 10.4m

hmm.. very blurry repost please

Step-by-step explanation:

Answer:

-47

Step-by-step explanation:

in negative numbers the higher you go, the lower it is.

think of opposites, this least to greatest: -47, -24, -18, -8, ok, so you can see that -47 is the least.

Hope this helps you, have a great day.

Answer:

They are skew lines.

Step-by-step explanation:

Which statement is true about lines a and b?

They are parallel lines.

They are perpendicular lines.

They are skew lines.

They will intersect.

As they both are in different directions they are skew lines .

Skew lines are not parallel neither they .They are also not co planar i.e they lie in different planes.

We have two plane Q and R . We have two line a and b on the different planes Q and R. Both planes are parallel but the lines a and b are in different directions. Therefore they are skew lines . They do not intersect and are also not parallel neither co planar.

Answer:

1. spring

2. 21

3. 225

Step-by-step explanation:

102-123=21

all the numbers added equal 225

The solution is

A) The season which is least popular is Spring

B) The number of people who have more allergies than the non-allergic group is 21 people

C) The total number of people surveyed is 225 people

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the Allergic group be = A

Let the non-allergic group be = B

Now , the equation is given as

Allergic Group A = { Winter = 43 , Spring = 12 , Summer = 35 , Fall = 33 }

Non-Allergic Group B = { Winter = 21 , Spring = 13 , Summer = 33 , Fall = 35 }

A)

To find the lease popular season

Find the number in the group which has the least values

So , the Spring season of Group B has the least number of people

Therefore , the spring season of non-allergic group is least popular

B)

The total number of Allergic people = Total sum of Allergic group A

So , the equation will be

Sum of Group A = 43 + 12 + 35 + 33

Sum of Group A = 123 people

Now ,

Total number of non-allergic people = Total sum of non-allergic group B

So , the equation will be

Sum of Group B = 21 + 13 + 33 + 35

Sum of Group B = 102 people

So , the difference between Group A and Group B = 123 - 102

                                                                                     = 21 people

Therefore , a total of 21 people were more in allergic group

C)

The total number of people surveyed = Sum of Group A + Sum of Group B

So , the equation will be

The total number of people surveyed = 123 + 102

The total number of people surveyed = 225 people

Therefore , The total number of people surveyed is 225 people

Hence ,  

A) The season which is least popular is Spring

B) The number of people who have more allergies than the non-allergic group is 21

C) The total number of people surveyed is 225 people

Answer:

16.75 meters

Step-by-step explanation:

This problem is a plug in problem.

H = 0.20x + 12.75

we plug in 20 for x which gives us

(0.20 * 20) + 12.75

which equals

4 + 12.75

giving us

16.75 meters

Answer:

16.75 meters

Step-by-step explanation:

First of all, in this x=20

let's plug it in

y=0.20×20+12.75

y=4+12.75

y=16.75

Answer:

Equation → 5y = 3y + 6

Value of ST = 15

Step-by-step explanation:

From the picture attached,

In right triangles ΔVST and ΔVUT,

Acute angles ∠SVT ≅ ∠UVT [Given]

TV ≅ TV [By reflexive property of congruence]

ΔVST ≅ ΔVUT [Hypotenuse angle congruence of right triangles]

Therefore, corresponding parts of the congruent triangles are congruent.

Therefore, ST ≅ TU

5y = 3y + 6

5y - 3y = 6

2y = 6

y = 3

Therefore, ST = 5y

ST = 5(3)

     = 15
