Congruent triangles have congruent sides and angles. If ΔKMN≅ΔPRT (given) then from the diagram you can conclude that

  • KM≅PR;
  • MN≅RT;
  • KN≅TP.

If MN≅RT, then

3x-1=20,

3x=20+1,

3x=21,

x=21:3,

x=7.

Answer: x=7.

We are given that

triangle KMN and triangle PRT are congruent

so, their corresponding sides must be equal

so, we can get

KM=PR

MN=RT

NK=TP

we are given

KM=15

MN=20

NK=25

RT=3x-1

now, we can plug this value

MN=RT=3x-1

20=3x-1

now, we can solve for x

Add 1 on both sides

20+1=3x-1+1

21=3x

Divide both sides by 3

and we get

x=7..............Answer

if one angle in a pair of vertical angles measures 36degrees and the other measures (2n-8)degrees, which is the value of n ? ple
KiRa [710]

Answer:

n = 22

Step-by-step explanation:

Since they are vertical angles they are the same.

Therefore you can put together this equation:

2n - 8 = 36

Add 8 to both sides

2n = 44

Divide by 2

n = 22

Choose the equation that satisfies the data in the table.
KengaRu [80]

The equation that satisfies the data in the table is,

y = -4x - 4 [Option D]

Definition of an Equation:

An equation is defined as a mathematical assertion in which you use mathematical symbols to demonstrate the equality of two amounts. A combination of expressions with variables and constants on either side of the equality sign make up an equation.

The (x, y) coordinates from the given table are,

(-1,0), (0, -4), (1, -8)

Now, these points must satisfy the required equation.

Considering the first point (-1, 0), if we substitute these values of x and y coordinates in y=4x-4, the equality is no longer maintained.

Similarly, (-1,0) does not satisfy the second and third equations, that are, y = -x + 4 and y = x + 4, respectively, either.

Taking the fourth equation, y = -4x - 4

Putting x = -1 in this equation, we get,

y = -4(-1) - 4

y = 4 - 4

y = 0

Likewise, this equation satisfies the rest of the data in the table too.

Therefore, y = -4x - 4 is the required equation.
