ARE THESE TRIANGLES CONGRUENT?

Answer:

Step-by-step explanation:

From the given graph the line is straight ,so it means that the relation between x and y is directly proportional

(or) you can also say that at each point the slope of the line is same

slope =y/x ,  slope= 26/2  = 65/2 = 117/9 =13

hence slope is same that's why relation between x and y is direct relation

y∝ x

y=k*x

k=y/x

putt any point one the line to find the value of constant of proportionality,

i putt (2,26)

Answer:

A solution of the system of equation given in the question is;

(2) x = 7 and y = 23

Step-by-step explanation:

The given system of equation are;

2·x + 3·y = 83...(1)

y = 2·x + 9...(2)

Substituting the value of y = 2·x + 9 from equation (2) into equation (1) gives;

2·x + 3·y = 2·x + 3 × (2·x + 9) =  83

∴ 2·x + 6·x + 27 = 83

8·x = 83 - 27 = 56

x = 56/8 = 7

x = 7

By substituting the value of x = 7 derived above into equation (1), we have;

y = 2·x + 9

Where;

x = 7

y = 2 × 7 + 9 = 14 + 9 = 23

y = 23.

Answer:

x = 20

Step-by-step explanation:

added together, the angles make 180

3x + 80 + 2x = 180

subtract 80 from both sides of the equation

3x + 80 - 80 + 2x = 180 - 80

combine like terms

5x = 100

divide both sides by 5

5x/5 = 100/5

x = 20

Answer:

x = 20

Step-by-step explanation:

added together, the angles make 180

3x + 80 + 2x = 180

subtract 80 from both sides of the equation

3x + 80 - 80 + 2x = 180 - 80

combine like terms

5 x = 100

divide both sides by 5

5x/5 = 100/5

x = 20

Answer:

The expressions are;

-5(x)(y)

8-y/x

Step-by-step explanation:

Here, we want to select expressions on the table having a solution of 10, given the value of x and y

For ;

-x(10) = -1(10) = -10

x + y + 7

-1 +2 + 7 = 8

8 -y/x = 8-(2/-1) = 8 + 2 = 10

-5(x)(y)

= -5(-1)(2) = 10

16-x + y - 7

16-(-1) + 2 - 7

16 + 1 + 2 - 7 = 12

Answer:

the answer is (x-5) (x+2)

Answer:

A is 20°

Step-by-step explanation:

Given sin3A = (√(3))/2. To find A we firstly take the sin^-1 of both sides and we have:

3A = sin^-1(√(3)/2)

We know that sin60° = √(3)/2. Therefore, sin^-1(√(3)/2) = 60°. Hence, we have

3A = 60°.

To get A, divide both sides by 3:

.A = 20°. Therefore, A is 20°.

The cosine of Ø is: [tex]\frac{1}{2}[/tex]

The ordered pair of a unit circle is represented as:

[tex](x,y) \to (\cos(\theta),\sin(\theta))[/tex]

The given parameters can be represented as:

[tex](x,y) \to (\frac{1}{2},\frac{\sqrt 3}{2})[/tex]

Recall that:

[tex](x,y) \to (\cos(\theta),\sin(\theta))[/tex]

Compare the above representation to:

[tex](x,y) \to (\frac{1}{2},\frac{\sqrt 3}{2})[/tex]

This means:

[tex]\cos(\theta) = \frac{1}{2}[/tex] and [tex]\sin(\theta) = \frac{\sqrt 3}{2}[/tex]

Answer:

A) 6 x² - 7x - 20

Step-by-step explanation:

Explanation:-

Given p(x) = 2 x-5 and r (x) = 3 x +4

(pr)(x) = p(x) r(x)

         = (2x -5)( 3 x +4)

        = 2x(3x +4) -5( 3x +4)

       = 6 x² + 8x - 15 x - 20

       =  6 x² - 7x - 20

(pr)(x) = 6 x² - 7x - 20

Answer:

what class is this ???

Step-by-step explanation:

The value of each measure are,

8. ED = 16 ft

9. DF = 21 ft

10. m ∠DEF = 103°

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

Given that;

In trapezoid DEFG,

⇒ EG = 21 ft and m ∠DGF = 77°

Now, We know that;

In trapezoid, The sum of the angles on the same side is equal to 180°.

Hence, We get;

⇒ ∠ DGF = ∠ GDE = 77°

And, We get;

⇒ ∠ DEF + ∠ EDG = 180°

⇒ 77° + ∠ DEF = 180°

⇒ ∠ DEF = 180° - 77°

⇒ ∠ DEF = 103°

Since, In trapezoid opposite non parallel line are equal in length.

Hence, We get;

⇒ ED = FG

⇒ ED = 8 + 8

⇒ ED = 16

In trapezoid, Diagonal are equal in length.

Hence, We get;

⇒ DF = EG

⇒ DF = 21 ft

Explaination

3 +4=7[1]    x = -4y + 7

// Plug this in for variable  x  in equation [2]

  [2]    4•(-4y+7) - 3y = 9

  [2]     - 19y = -19

// Solve equation [2] for the variable  y

  [2]    19y = 19

  [2]    y = 1

// By now we know this much :

   x = -4y+7

   y = 1

// Use the  y  value to solve for  x

   x = -4(1)+7 = 3

let the length of the rope be x=???

Applying Pythagoras theorem

x^2=h^2+l^2

x^2= 9^2+12^2

x^2= 81+144

x^2=225

square both sides

x=√225

x=15 m
