Answer:

? is 59 degrees

Step-by-step explanation:

the two angles created by the intersecting lines are vertical angles and are equal

also, we know there are a total of 180 degrees in a triangle, so

180 - (21 + 49) = 100

this will help us find '?' because we can add 21 and 100, to get 121, then deduct 121 from 180 to get the value of ? which is 59

The quadrilateral is parallelogram because the opposite sides are parallel and congruent

What is a parallelogram?

A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure. Also, the interior angles on the same side of the transversal are supplementary. The Sum of all the interior angles equals 360 degrees.

Since WZ and XY are congruent and XW and YZ are congruent and Also, WZ and XY are parallel and XW and YZ are parallel, we can therefore say that the quadrilateral obeys the property of a parallelogram.

Work out the value of x.​

Answers

Answer:

  x = 4 . . . cm

Step-by-step explanation:

You want the measure of the segment CE from external point C to circle O, given several other dimensions of chords and segments in the circle.

Crossing chords

As in the attachment, we can extend segment DO across the circle to make diameter DX. Then we can use the relation for chord lengths to find the radius of the circle (r).

Segments of crossing chords have the same product:

  FA·FE = FD·FX

  7·4 = 2·(2r -2) . . . . . use given segment values

  14 = 2r -2 . . . . . . divide by 2

  16 = 2r . . . . . . . add 2

  r = 8 . . . . . . . divide by 2

The radius of the circle is 8 cm.

Secants

We can also extend radius EO across the circle to make diameter EY, as shown in the attachment.

The relation involving the product of secant segments can be used to find x:

  CE·CY = CB·CA

  x(x +16) = 5(5+4+7)

  x² +16x = 80 . . . . . . . . simplify

  x² +16x +64 = 144 . . . . . . . add 64 to complete the square

  (x +8)² = 12² . . . . . . . . . write as squares

  x +8 = 12 . . . . . . . . positive square root

  x = 4 . . . . . . . . subtract 8

The value of x is 4.

Which of the follow is a solution set for the following graph

Answers

The solution set for the given graph is (2,1). The solution has been obtained using linear equations.

What is a linear equation?

It is a linear equation that has the greatest degree of one. In a linear equation with an exponent greater than one, this indicates that there are no variables. A straight line is produced on the graph by this equation.

We are given two lines on the graph

The points of the red line are (3,0) and (0,3)

So, the equation of the line comes out to be

y=−x+3      ...(1)

The points of the blue line are (3,2) and (-1,-2)

So, the equation of the line comes out to be

y=x−1     ...(2)

To find the solution set, we need to solve the equations

Substituting (1) in (2), we get,

⇒−x+3 = x−1

⇒−2x = -4

x = 2

So, y = 1

Hence, the solution set for the given graph is (2,1).

The results of the function are shown by the dependent variable (y). In an experiment, a variable that stands in for a variable being changed is known as an independent variable.As the independent variable in an equation, x is frequently employed as its symbol.

N(u) = 4, where N is the function and u is the independent variable, is the function that is provided.

Since u is no longer a variable, the value of the function N(u) is now a constant.

How to solve the system of equations?

Here we want to solve the system of equations below:

y = -5x + 21

-4x + y = 6

We can use the elimination method to solve this if we take the difference between the two equations, we will get:

y - (-4x + y) = -5x - 21 - 6

4x = -5x - 27

Now we can solve this for x.

4x + 5x = -27

9x = -27

x = -27/9 = -3

And the value of y is given by:

y = -5x - 21  (we need to evaluate that on x = -3)

∠ARU angle = 40°

AU length = 20°

A diagram is included here.

AR is the angle bisector of angle URK.

As a result, ∠ARU = ∠ARK = 40°.

Because the incenter point is equidistant from the triangle's sides.

As a result, AT = AU = AK = 20.

Because PA is the angle bisector of angle QPU.

As a result, ∠QPA = ∠UPA.

3x + 2 = 4x - 9

there are five boys to every six girls in an introductory geology course. if there are 374 students enrolled in the course, how many are boys?

Answers

The total number of boys enrolled in the course is 170.

Here are 374 children, are there are 5 boys to every 6 girls.

If the ratio of boys to girls is 5 to 6, then 5 out of every 11 students are boys and 6 out of every 11 students are girls.

Set up a proportion for the boys, where b = the total number of boys.

5/11 = b/374

11b = 1870

b = 1870/11

b = 170

There are 170 boys.

The total number of student is 374, so the number of girls, is 374 -b.

There are 374-170= 204 girls.

Finding a proportionality constant would be another algebraic solution to this issue. The total number indicated by the ratio is 5 + 6 or 11, which is equal to the total number of children when multiplied by the proportionality constant.

Let x = the proportionality constant

11x=374

x=34

The number of boys is 5x and the number of girls is 6x.

5x=5×34 =170 boys
