The value of x = - 12°

The triangle which has two equal sides or two equal sides is called an Isosceles triangle. In a Isosceles triangle the angles made by equal sides with 3rd side will be equal

Here from given question we have,

Measure of ∠2 = x + 85

And the measure of another angle = 73

From given picture,

Two sides of triangle are equal then the given triangle will be an Isosceles triangle

As we know in a Isosceles triangle the angles made by the two equal sides with 3rd side will be equal  

=> ∠2 = 73

=> x + 85 = 73

=> x = - 85 +73

=> x = -12°

Therefore,

The value of x = -12°

Explanation

to plot this, you need to count the numbers of weigth for that number, for example

for 18

count in the table all the 18

you will get 18 is 2 times in the table (2)

now, for 19

count the number of 19's in the table 3

and so on

Step 1

then, for 24

total = 0

so, as we have not 24 as a data, there is not need to plot it

I hope this helps you

Coordinates are a pair of integers (Cartesian coordinates), or sporadically a letter and a number, that identify a certain place on a grid, also referred to as a coordinate plane.

The x-axis & y-axis are the two axes that make up a coordinate plane (vertical).

The coordinates of the origin, which is the location where the two axes connect, are (0, 0).

The graph of the parabola is added as an attachment

From the complete question (added at the end of the solution), the equation of the parabola is given as

y = x²

When a parabola has the form of y = x², then the vertex of the parabola is

Vertex = (0, 0)

Set x > 0 to determine the points to the right

When x = 1

y = 1² = 1

When x = 2

y = 2² = 4

Set x > 0 to determine the points to the left

When x = -1

y = -1² = 1

When x = -2

y = -2² = 4

So, the points are

(1, 1), (2, 4), (-1, 1) and (-2, 4)

While the vertex is (0, 0)

Next, we plot the graph of the parabola using a graphing calculator

Multiply the full number by the denominator to convert a mixed number to an improper fraction. If the value be 3 11 / 16 then simplifying the value 59 / 16.

Multiply the full number by the denominator to convert a mixed number to an improper fraction. Include it in the numerator. Add that total to the denominator from the beginning.

To make a mixed number from an improper fraction, divide the numerator by the denominator. After division, the mixed number is produced in such a way that the obtained quotient becomes the entire number, the remainder becomes the new numerator, and the denominator remains constant.

Let the value be 3 11 / 16

Convert mixed numbers to improper fraction: [tex]$a \frac{b}{c}=\frac{a \cdot c+b}{c}$[/tex]

[tex]$&3 \frac{11}{16}=\frac{3 \cdot 16+11}{16}=\frac{59}{16} \\[/tex]

= 59 / 16

Therefore, the correct answer is 59 / 16.

Solving for x:

In this case, the answer is very simple.

Defines substitution.

The answer is:

The substitution method for solving systems of linear equations, consists of solving or isolating one of the unknowns (for example, x) and substitute its expression in the other equation.

In this way, we will obtain a first degree equation with the other unknown (y), and once solved ''y'', we calculate the value of ''x'' substituting the value of ''y'', that we already know.

The unitary approach, to put it simply, is used to determine the value of a single unit from a specified multiple. How to determine the worth of a single pen, for instance, if 40 pens cost Rs. 400. The unitary approach can be utilized. Additionally, after determining the value of a single unit, we can multiply it to determine the value of the other units. Most ratio and proportion concepts are addressed using this methodology. To compute the value of other units using the unitary approach, the value of a unit quantity must first be determined. This can be varied in two different ways.

3 days = 22 miles

1 day = x

x = 7.4 miles

Still 12 miles are left so I will need half a day more approximately.

The true statement is b.

The equation of the parabola with a vertex at the origin and a directrix at; y = 5 as described in the task content is; x² = -20y.

It follows from the task content that the vertex of the parabola is at the origin while it's directrix is the line; y = 5.

Therefore, it follows that the focus of the parabola is; f = -5, since; (f - k) = (k - 5) where, k = 0.

Ultimately, a = 1/4(f-k).

a = 1/4(-5-0) = -1/20.

Recall, the vertex form equation of a parabola takes the form;

y = a(x - h)² + k; where (h, k) is the vertex.

Therefore, since the vertex is at the origin; we have;

y = (-1/20) (x -0)² + 0

y = -x²/20

20y = -x²

Ultimately, the required equation of the parabola is;

x² = -20y.

Answer:

[tex]y = -\frac{1}{20} x^{2}[/tex]

Step-by-step explanation:

[tex]y = \frac{1}{4(f-k)}(x - h)^{2} + k[/tex] Use the equation of the parabola. The vertex is at the origin, then (h, k) is (0, 0). Substitute 0 for h and k in the equation.

[tex]y = \frac{1}{4(f-0)} (x-0)^{2} + 0[/tex] Simplify.

[tex]y = \frac{1}{4f} x^{2}[/tex]

The directrix is given [tex]y = 5[/tex]. The distance from the focus to the vertex equals the distance from the vertex to the directrix, so

[tex]f - k = k - 5\\f = -5[/tex] Substitute -5 for f  in the equation of the parabola above.

[tex]y = \frac{1}{4 * - 5} x^{2}[/tex] Simplify.

Answer:

6. C

7. 105 ft²

Explanation:

The square pyramid has a square base with a side's length equal to 5 ft and a slant height equal to 8 ft.

Now, the only option that shows a square with a side length equal to 5 is C. So, the right net is C.

Then, the amount of fabric depends on the area of the net. The area of the net is equal to the area of the square added to the area of the triangles.

The area of the square is:

Area = side x side = 5 x 5 = 25 ft²

The area of the triangles is:

Area = 1/2 x base x height = 1/2 x 5 x 8 = 20 ft²

Then, the total area of the net is:

Total Area = 25 ft² + 4( 20 ft²)

Total Area = 25 ft² + 80 ft²

Total Area = 105 ft²

So, Frank needs 105 ft² of fabric to make the fort.
