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

Therefore,

x = 46.40°

The statement is true. Multiplication is commutative, which means that the order of multiplication does not affect the result.

The statement "0 x 5 = 5 x 0" is true because of the commutative property of multiplication. In multiplication, the order of factors does not change the result.

When we multiply 0 by 5, it equals 0 since anything multiplied by 0 is 0. Similarly, when we multiply 5 by 0, the result is still 0. Both expressions are equal to 0, confirming the commutative property.

In summary, 0 x 5 and 5 x 0 are interchangeable and yield the same result, proving the truth of the statement based on the fundamental property of multiplication.

An element of a line known as a line segment joins two places that are thought of as line's ends. Point C is on line segment BD, Given CD = 2 and BC = 8, the length BD is 10.

A line segment in geometry is a section of a straight line that is enclosed by two clearly defined end points and contains all of points on the line that lie inside those endpoints. The Euclidean distance between the two ends of a line segment determines its length. Half-open line segments contain exactly one of endpoints, while closed line segments have both of the endpoints. Open the line segments do not contain either of the endpoints. A line drawn above the symbols for the two endpoints is frequently used in geometry to indicate a line segment.

An element of a line known as a line segment joins two places that are thought of as line's ends. It is possible to measure the separation between two places. Given that line segments have a defined length, they can form the sides of any polygon.

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

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

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°

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)
