The value of [x] in the triangle is 36.25°.

In Euclidean geometry, a parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. A triangle is a polygon with three edges and three vertices. The sum of all the angles of a triangle is 180 degrees. Mathematically -

∠x + ∠y + ∠z = 180°

There are different types of triangles such as -

equilateral triangle , scalene triangle , isosceles triangle etc.

Given is a right angled triangle.

We can write -

tan(x°) = (22/30)

x° = tan⁻¹(22/30)

x° = 36.25°

Therefore, the value of [x] in the triangle is 36.25°.

What is sinusoidal wave?

A mathematical curve defined in terms of the sine trigonometric function, of which it is the graph, is known as a sine wave, sinusoidal wave, or simply sinusoid. It is a smooth periodic function and a particular kind of continuous wave.

Let the graphs of y = cos(x) and y = cos(x/2) are given.

From this graphs we have to find the value of c and d.

First from y = cos(x) to find the value of 'a'.

Consider, the point  [tex](a, \frac{1}{8})[/tex]

⇒

[tex]cos(a) = \frac{1}{8} \\a = cos^-^1(\frac{1}{8})\\ a = 82.82[/tex]

Now to find the value of 'c'.

Plug a = 82.82 in y = cos(x/2).

[tex]cos(\frac{82.82}{2}) = c \\c = -0.84[/tex]

Hence, the value of 'c' is 'c = -0.84'.

Now to find the value of 'd'.

Consider, the point [tex](b, \frac{1}{8})[/tex]

⇒

[tex]cosb = \frac{1}{8} \\b = cos^-^1(\frac{1}{8})\\b = 82.82[/tex]

Now, plug b = 82.82 in y = cos(x/2)

[tex]cos(\frac{82.82}{2}) = d\\ d = 0.84[/tex]

Hence, from the given graphs the values of 'c' and 'd' are c = -0.84,

d = 0.84.

Answer:

Step-by-step explanation:

The angles BAX and CDX are equal and the length of CX is 8.2 cm.

What are angles?

An angle is a figure in plane geometry that is created by two rays or lines that have a shared endpoint. The Latin word "angulus," which meaning "corner," is the source of the English term "angle." The shared terminus of two rays is known as the vertex, and the two rays are referred to as sides of an angle.

Given that, the points A, B, C, D lie on a circle and AC and BD intersect at X.

The angles BAX and CDX, they are subtended by the same arc AD, hence, according to the property of angles subtended by the same arc, they are equal.

Thus ∠BAX = ∠CDX

Since, corresponding sides opposite to the equal angles are proportional.

CX/BX = CD/AB

⇒ CX/3.84 = 9.40/4.40

⇒ CX = (9.40*3.84)/4.40

⇒ CX = 8.2

Thus, length of CX is 8.2cm

The angles BAX and CDX are equal and the length of CX is 8.2 cm

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 number of chickens in the farm be = x

Let the number of cows in the farm be = y

Now , the total number of animal heads in the farm = 43

So , the equation will be

x + y = 43   be equation (1)

Now ,

The total number of cow legs = 124

The number of legs for cows = 4

So , the equation will be

4y = 124

Divide by 4 on both sides of the equation , we get

y = 31   be equation (2)

Now , the value of y is 31 , substitute the value of y in equation (1) , we get

x + y = 43

x + 31 = 43

Subtracting 31 on both sides of the equation , we get

x = 12

And , the value of x is 12

Therefore , the number of chickens is 12 and number of cows is 32

Hence , The number of chickens in the farm = 12 chickens

The number of cows in the farm = 32 cows

Answer:

90 units²

Step-by-step explanation:

The scale factor of the lengths of the sides of a solid must be squared to to find the ratio of the areas and cubed to find the ratio of the volumes.

For example, if you are given two solids with a scale factor of the lengths of the sides of 2, meaning that the sides of the second solid are twice the length of the sides of the first solid, then the surface area of the second solid is 2² (= 4) times the surface area of the original solid, and the volume of the second solid is 2² (= 8) times the volume of the original solid.

Let's say you have a cube with edge of 1 cm. The volume is (1 cm)³ = 1 cm³.

The surface area is the sum of the areas of the 6 faces which are squares 1 cm by 1 cm. 6 × (1 cm)² = 6 × 1 cm² = 6 cm².

The original cube with edge of 1 cm has a volume of 1 cm³ and total surface  area of 6 cm².

Now double the size of the edge of the cube. The new cube has an edge of 2 cm. The volume is (2 cm)³ = 8 cm³. Each face of the cube is a square 2 cm by 2 cm. The total surface area of the new cube is 6 × (2 cm)² = 24 cm².

The new cube has volume 8 cm³ and total surface area 26 cm².

Compare the edges, surface areas and volumes of the two cubes:

                             Original Cube     Dilated Cube    Ratio new/dilated

Edge                              1 cm                    2 cm                    1:2

Surface area                 6 cm²                 24 cm²                 1:4

Volume                          1 cm³                  8 cm³                   1:8

Now here is your problem.

We start with the ratio of the volumes.

Original solid: 128 u³

Dilated solid: 54 u³

ratio of volumes: 54/128 = 27/64 = 3³/4³

The ratio of volumes is the cube of the ratio of the lengths.

ratio of lengths: 3/4

ratio of area: 3²/4² = 9/16

Surface area of original solid: 160 u² × 9/16 = 90 u²

a) The area of Helen's circular garden is 314 m².

b) The estimation for the number of boxes of grass seed Helen needs, is 5 boxes.

c) B. The estimation we did in (b) is an underestimation.

The area of a circle is calculated by the formula,

A = πr² sq. units; r - radius

When we have the diameter, we can find the radius by

r = d/2 units

Given that Helen has a garden in the shape of a circle of diameter 20 m.

She is going to cover the garden with grass seed to make a lawn.

Grass seed is sold in boxes. Each box of grass seed will cover 58 m² of the garden.

a) The area of the circular garden is

A =  πr² = 3.14 × (d/2)²

⇒ A = 3.14 × (20/2)²

⇒ A = 3.14 × 100

∴ A = 314 m²

Thus, the area of Helen's garden is 314 m².

b) The number of boxes of grass seed to cover the area of 314 m² is

= area of the garden/area covered by each box of seeds

= 314 m²/58 m²

= 5.4179

So, on an estimation, there are 5 boxes of grass seed that Helen needs.

c) Here, in the above estimation, we rounded the decimal number 5.4179 to 5. Since the number is rounded to the nearest value (smallest value), the estimation is an underestimate.

The length of the given rectangle is 7 units.

The area of the rectangle is the product of its length and width.

I.e., A = l × w sq. units

It is given that, the width of a rectangle is the length minus 6 units.

I.e., W = L - 6 units

Then, the area of the rectangle is

A = L × (L - 6)

But we have given that, the area of the rectangle is 7 sq. units.

So, we can write

7 = L² - 6L

⇒ L² - 6L - 7 = 0

⇒ L² - 7L + L - 7 = 0

⇒ L(L - 7) + 1(L - 7) = 0

⇒ (L + 1)(L - 7) = 0

∴ L = -1 or L = 7

The length should not be a negative value. So, the length of the given rectangle is 7 units.

Then, the width of the rectangle is

W = L - 6 = 7 - 6 = 1 unit.

Step-by-step explanation:

You want an expression using an exponent to represent the number 3·3·3.

As you know, a coefficient is used to represent repeated addition:

  a + a + a = 3a

The coefficient 3 in the above expression signifies that 'a' appears in the sum 3 times.

Likewise, repeated multiplication can be represented using a specific notation. An exponent signifies the number of times a factor appears in a product:

  a · a · a = a³ . . . . . 'a' is a factor 3 times

You have a sequence of numbers of telephone calls:

  3 the first day

  3·3 the second day

  3·3·3 the third day

The calls on the third day can be represented using an exponent:

  3³

__

Additional comment

When superscript formatting is not available for the exponent, it is signified by a caret (^). The same number is 3^3 when written in plain text.

As you might expect, a plain text exponent must be enclosed in parentheses if it is other than a single letter or number.
