Answer:

123 degrees

Step-by-step explanation:

Angles in a quadrilateral add up to 360 degrees

so we add all the angles

114 + 80 + 43 which is 237

360 - 237 is 123

so angle x is 123 degrees

Answer:

54 degrees

Step-by-step explanation:

This is trigonometry. So we are given the adjacent leg and hypotenuse. So we can use cosine(cah from soh cah toa)

We will have to use the inverse of the trig ratios.

Remember!

cos^-1 is not 1/cos(that is sec)

cos^-1(27/46)

acos(27/46)

6/8

3/4

Step-by-step explanation:

Answer:

The answer is 3/4.

Step-by-step explanation:

1/2+1/4

First we want to get a common denominator so that they can be added together.

1/2 * 2/2 = 2/4

We multiplied 1/2 by 2/2 so that both terms have a denominator of 4. Note that we also multiplied the top and bottom of 1/2 because we have to keep the value of the fraction the same.

Now we just add the fractions together.

2/4 + 1/4 = 3/4

So 3/4 is the answer. It is already in its simplest form meaning it cannot be simplified further.

Answer:

140, 60

Step-by-step explanation:

15x+5 + < CDB =180 line form an 180 angle

180-80-6x-6 = < CDB sum of angles in a triangle is 180

substitute < CDB from second to first

15x+5+180 -80-6x-6 =180

combine like terms

9x -81 =0

x=81/9=9

so angle YDC = 15*9+5 = 140 degrees

and angle DBC = 6*9+6= 60 degrees

Answer:

[tex]\displaystyle h=-\frac{1}{6}x^2+2x[/tex]

Step-by-step explanation:

We are given that the height of the tunnel is modeled by:

[tex]h=rx^2+tx[/tex]

Where r and t are constants.

We are also given that the maximum height of the tunnel h is six meters.

And at ground level, the width is 12 meters.

And we want to determine the equation of the parabola.

First, since this is a quadratic, our maximum height h will occur at the vertex of our equation.

Recall that the vertex is given by the formulas:

[tex]\displaystyle \text{Vertex} = \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]

In our case, we have the function:

[tex]h=(r)x^2+(t)x[/tex]

Hence, a = r; b = t; and c = 0.

Therefore, the x-coordinate of our vertex is:

[tex]\displaystyle x = -\frac{t}{2r}[/tex]

Therefore, if we substitute this back into our equation, the result should be six since six is the maximum height. Hence:

[tex]\displaystyle (6)=r\left(-\frac{t}{2r}\right)^2+t\left(-\frac{t}{2r}\right)[/tex]

Simplify:

[tex]\displaystyle 6=r\left(\frac{t^2}{4r^2}\right)-\frac{t^2}{2r}[/tex]

Simplify:

[tex]\displaystyle 6=\frac{t^2}{4r}-\frac{t^2}{2r}[/tex]

Subtract:

[tex]\displaystyle 6=\frac{t^2}{4r}-\frac{2t^2}{4r} = -\frac{t^2}{4r}[/tex]

Multiply:

[tex]\displaystyle 24r=-t^2, \, r\neq 0[/tex]

Solve for r:

[tex]\displaystyle r=-\frac{t^2}{24}[/tex]

Next, we are given that the width is 12 meters at ground level.

Hence, when h = 0, the difference of our roots is 12:

We have:

[tex]0=rx^2+tx[/tex]

Factor:

[tex]0=x(rx+t)[/tex]

By the Zero Product Property:

[tex]x=0\text{ or } rx+t=0[/tex]

Hence, the first zero is 0.

Therefore, the second zero must be 12 to ensure that our width is 12.

Let's isolate the second zero. Subtract t from both sides:

[tex]rx=-t[/tex]

Divide both sides by r:

[tex]\displaystyle x=-\frac{t}{r}[/tex]

We know that this zero must be 12. Thus:

[tex]\displaystyle 12=-\frac{t}{r}[/tex]

We have previously solved for r. Substitute:

[tex]\displaystyle 12=-\frac{t}{-\dfrac{t^2}{24}}[/tex]

Simplify:

[tex]\displaystyle 12=\frac{24}{t}[/tex]

Take the reciprocal of both sides:

[tex]\displaystyle \frac{t}{24}=\frac{1}{12}[/tex]

Multiply. Hence, the value of t is:

[tex]t=2[/tex]

Find r. Recall that:

[tex]\displaystyle r=-\frac{t^2}{24}[/tex]

Therefore:

[tex]\displaystyle r=-\frac{(2)^2}{24}=-\frac{4}{24}=-\frac{1}{6}[/tex]

Then in conclusion, our equation will be:

[tex]\displaystyle h=-\frac{1}{6}x^2+2x[/tex]

Answer: A

Step-by-step explanation:

The proof that is not needed John's proof is When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent

The following proof are needed.

m∠4 + m∠2 + m∠5 = 180° (sum of angles on  a straight line)

∠4≅∠1  and ∠5≅∠3 (alternate interior angles)

Therefore,

∠1  can replace ∠4 and ∠3 can replace ∠5

m∠1 + m∠2 + m∠3 = 180°

Therefore, When two parallel lines are cut by a transversal, the resulting alternate exterior angles are congruent is not needed.

Step-by-step explanation:

1750 for his diet

1750 x 7 = 12,250

14,000 - 12,250 = 1750

Answer:

1. Multiply (2) by 2 to eliminate the x-terms when adding

2. Multiply (2) by 3 to eliminate the y- term

Step-by-step explanation:

Use this system of equations to answer the questions that follow.

4x-9y = 7

-2x+ 3y= 4

what number would you multiply the second equation by in order to eliminate the x-terms when adding the first equation?

4x-9y = 7 (1)

-2x+ 3y= 4 (2)

Multiply (2) by 2 to eliminate the x-terms when adding the first equation

4x-9y = 7

-4x +6y = 8

Adding the equations

4x + (-4x) -9y + 6y = 7 + 8

4x - 4x - 3y = 15

-3y = 15

y = 15/-3

= -5

what number would you multiply the second equation by in order to eliminate the y- term when adding the second equation?

4x-9y = 7 (1)

-2x+ 3y= 4 (2)

Multiply (2) by 3 to eliminate the y- term

4x - 9y = 7

-6x + 9y = 12

Adding the equations

4x + (-6x) -9y + 9y = 7 + 12

4x - 6x = 19

-2x = 19

x = 19/-2

= -9.5

x = -9.5
