C is rotation

Picture A represents the translation, the picture represents the reflection, and picture C represents the rotation.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

It is given that:

The lines are shown in the picture.

As we know from the definition of the geometric transformation, geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

From the picture,

Picture A, which is being moved to the right to obtain A'B', serves as a representation of the translation.

Because you would reflect over the x-axis, Picture A represents reflection.

Answer: 65.97

Step-by-step explanation:

The value of x in the triangle is 46.40° .

The angle of a triangle can be found using sine rule.

Therefore, applying sine rule,

a / sin A = b / sin B = c / sin C

Hence,

5 / sin x = 6.9  / sin 88°

cross multiply

5 sin 88° = 6.9 sin x

5 × 0.99939082701 = 6.9 sin x

4.9969541351 = 6.9 sin x

divide both sides by 6.9

sin x = 4.9969541351  / 6.9

sin x = 0.72419625146

x = sin⁻¹ 0.72419625146

x = 46.4020264383

ATTACHED IS THE SOLUTION

Answer:

a = -2

b = -3

c = 2

Step-by-step explanation:

a*b = 6     {The product of a and b is 6]

a*c = -4     [The product of a and c is -4]

b*c = -6     [The product of b and c is -6]

-  Rearrange:

 1)   a*c = -4 to a = (-4/c)

 2)  b*c = -6 to b = (-6/c)

Now substitute:

a*b = 6

(-4/c)*(-6/c) = 6

(24/c^2) = 6

c^2 = (24/6)

c^2 = 4

c = 2

use this value of c to find a and b:

a = (-4/c)

a = (-4/2)

a = -2

b = (-6/c)

b = (-6/2)

b = -3

The equation or tape diagram could be used to represent the context if x represents the number of miles in the taxi ride is A. 29.95 - 1.2 / 1.25 = x

From the information, Houa took a taxi from her house to the airport and the taxi company charged a pick-up fee of $1.20 plus $1.25 per mile. The total fare was $29.95,

Let the number of miles be represented by x.

Therefore, the information will be illustrated by:

1.20 + 1.25(x) = 29.95

1.20 + 1.25x = 29.25

Find the probability of pulling a red card out of a standard deck of cards

Step-by-step explanation:

So, the probability of drawing a red-faced card is 6 out of 52 cards. Thus, the probability of drawing a red face card from a deck of cards is 6/52 = 3/26.

A standard deck of playing card consists 52 cards.

Cards is splitted into 4 suit i.e. Hearts, Spades, Diamond and Clubs.

Each suits consists of 13 cards - the Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, King and Queen.

Hearts & Diamond are red cards and Spades and Clubs are black cards.

Probably = Number of favourable/Possible outcomes/ Total outcomes.

Probability of pulling a red card = 26/ 52 = 0.5

Answer:

The height of pole is 20√3 m each and distance of pole from the point on road is 60 m and 20 m respectively.

Step-by-step explanation:

Given:

To Find:

Formula used:

Let the height of each pole be H metres.

Also, let's assume that distance of the point from one pole (as shown in figure) be x m.

According to question, we have

tan60° = H/(80-x)

H = (80-x)√3.... (1)

Also, tan30° = H/x

H = x/√3... (2)

Putting value of eq(2) in eq(1), we get

x/√3 = (80-x)√3

x = 3(80-x)

x = 240 - 3x

4x = 240

x = 60 m

Putting value of x in eq(2), we get

H = 60/√3 = 20√3 m

So, the height of pole is 20√3 m each and distance of pole from the point on road is 60 m and 20 m respectively.

Answer:

Height of Pole: 20√3 m

Distance Of Point From Poles: 20m and 60m

Step-by-step explanation:

The attached graph may help you understand my explanation better

The two poles are Ab and CD and are 80m apart

O is the point between them

The angle of elevation from O to A is 60°

The angle of elevation from O to D is 30°

Since the two poles are given to be of equal height,

AB = CD

In ΔAOB using the law of tangents

tan 60° = AB/BO

tan 60° = √3 and AB = x

So we get

√3 = x/BO

Multiplying both sides by BO we get

√3 · BO = x

or BO = x/√3

Looking at ΔCOD

tan 30° = DC/OC

tan 30° = 1/√3

1/√3 = x/OC

OC · ( 1/√3) = x

OC = x ÷ 1/√3

= x · √3/1

OC = √3x

We also know that BO + OC = 80

Plugging this information with values computed gives us

x/√3 + √3x = 80

Multiply by √3 on both sides

(x/√3) · √3 +  (√3x) √3 = 80√3

(x/√3) · √3 = x since the √3 terms cancel out

(√3x) √3 = 3x

So we get

(x/√3) · √3 +  (√3x) √3 = 80√3

=>
x + 3x = 80√3

4x = 80√3

x = (80√3)/4

x =20√ 3

So the height of each pole = 20√ 3 m ≈ 34.64 m

The distance OC can be found from the previous equation
OC = √3x

=> OC = √3 x 20√3 = 20 x 3 =  60m

Since BO + OC = 80 m

BO = 80 - 60 = 20 m

Answer:
Height of each pole = 20√3 m

The point is located 20 m from one pole and 60 m from the other pole

The value of z in this convex polygon is equal to 66°

A polygon can be defined as a two-dimensional geometric shape that comprises straight line segments and a finite number of sides.

Note: The number of sides (n) of a pentagon is 5.

In Geometry, the sum of all the interior angles of a polygon with "n" sides is given by this formula:

Interior angle = 180 × (n - 2)

Interior angle = 180 × (5 - 2)

Interior angle = 180 × 3

Interior angle = 540°.

Now, we can determine the value of z as follows:

(180° - 2z) + (180° - z) + 130° + 108° + 140° = 540°

3z - 378° = 540° - 360°

3z = 378° - 180°

3z = 198°

z = 198°/3

z = 66°
