For Exercises 8 and 9, find the lengths of all three sides of the triangle.

Draw and label a diagram.

sin A = CB / AB

cos B = CB / AB

sin A = cos B

2x - 1.3 = 5x

Can you solve for x and answer?

The value of expression sin C - cos C is,

⇒ r - s

Triangle is a three sided polygon, which has three vertices and three angles and which has sum 180 degrees.

Given that;

In right triangle ABC,

⇒ m∠ B ≠ m∠ C.

Let us assume that,

⇒ sin B = r

And, cos B = s.

Now, We get;

sin B = rh / h

        = r

And, cos B = sh / h

                 = s

Hence, We can formulate;

sin C = sh / h = s

cos C = rh / h = r

Thus, We get;

⇒ sin C - cos C

⇒ r - s

Therefore, The value of expression sin C - cos C is,

⇒ r - s

Answer:

8...

Step-by-step explanation:

Answer:

x + y = 35  equation 1

x + 2y = 62  equation 2

He made 8 1 point free throw

He made 27 2 point field goal

Step-by-step explanation:

let x = 1 point free throw

y = 2 point field goal

two equations can be derived from the question

x + y = 35  equation 1

x + 2y = 62  equation 2

Subtract equation 1 from 2

y = 27

Substitute for x in equation 1

x = 35 - 27 = 8

He made 8 1 point free throw

He made 27 2 point field goal

Answer: 140cm²

Step-by-step explanation:

Perimeter of a rectangle is calculated as: = 2(length + width)

where,

Length = x+4

Width = x

Therefore, perimeter = 2(length + width)

2(x + x+4) = 48

2(2x + 4) = 48

4x + 8 = 48

4x = 48 - 8.

4x = 40

x = 40/4

x = 10cm

The other side = x+4 = 10+4 = 14cm

Area = length × width

Area = 10cm × 14cm

Area = 140cm²

The answer would be 13.25 :)).

Answer:

She made eight 2 pointers

She made four  3 pointers

Step-by-step explanation:

2x + 3y = 28

x + y    = 12                 Multiply this equation by 2

2x + 2y =24

Write the first and third equations underneath each other,

2x + 3y = 28

2x + 2y = 24              Subtract.

        y = 4

x + y = 12

x + 4 = 12                     Subtract  4 from each side

   - 4    -4

x = 8

Answer:

  $35 per hour

Step-by-step explanation:

The total charge is the sum of costs of parts and labor. If h is the cost of a labor hour, then we have ...

  188.75 = 75 + 3.25h

  113.75 = 3.25h . . . . . . . . subtract 75

  113.75/3.25 = h = 35 . . . divide by the coefficient of h

The cost of labor, per hour, is $35.

Given:

Length of the building  = 120 feet

Width of the building = 40 feet

Length of the model = 6 feet

To find:

Width of the model.

Solution:

The scale model similar to the original figure and the corresponding sides of the similar figures are proportional.

Let x be the width of the building.

[tex]\dfrac{\text{Length of the building}}{\text{Length of the model}}=\dfrac{\text{Width of the building}}{\text{Width of the model}}[/tex]

[tex]\dfrac{120}{6}=\dfrac{40}{x}[/tex]

[tex]20=\dfrac{40}{x}[/tex]

[tex]x=\dfrac{40}{20}[/tex]

[tex]x=2[/tex]

Therefore, the width of the model is 2 feet.

Answer:

[tex]F'G' = 7[/tex]

Step-by-step explanation:

Given

[tex]F = (-2,4)[/tex]

[tex]G = (-2,-3)[/tex]

Required

Distance of F'G'

The transformation that give rise to F'G' from FG are:

The above transformations are referred to as rigid transformation, and as such the side lengths remain unchanged.

i.e.

[tex]F'G' = FG[/tex]

Calculating FG, we have:

[tex]FG = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]

Where:

[tex]F = (-2,4)[/tex] --- [tex](x_1,y_1)[/tex]

[tex]G = (-2,-3)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]FG = \sqrt{(-2 - -2)^2 + (4 - -3)^2}[/tex]

[tex]FG = \sqrt{(0)^2 + (7)^2}[/tex]

[tex]FG = \sqrt{0 + 49}[/tex]

[tex]FG = \sqrt{49}[/tex]

Take positive square root

[tex]FG = 7[/tex]

Recall that:

[tex]F'G' = FG[/tex]

[tex]F'G' = 7[/tex]

Answer:

Events A and B are dependent

Step-by-step explanation:

If A and B are two events such as A and B are dependent then

P(A∩B)  P(A) P(B)

An event A will occur with probability 0.4 that is  

An event B will occur with probability 0.6 that is  

The probability that both A and B will occur is 0.20 that is P(A∩B) = 0.20

Therefore,

P(A∩B)  P(A) P(B)

So,

events A and B are dependent
