I already try, please help clarify correct answer, thx

The value of x = 13

The value of KN = 23.5

Step-by-step explanation:

Here are some of the characteristics of a rectangle.

Given the diagonals of a rectangle

KM = 4x-15

KL = 9x-80

We know that the diagonals of a rectangle are equal, so

KL=KM

9x-80=4x-15

9x-4x= -15+80

5x = 65

divide both sides by 5

5x/5 = 65/5

x = 13

Therefore, the value of x = 13

as

KM = 4x-15

so substitute x = 13

KM = 4(13) - 5 = 52 - 5 = 47

From the diagram, it is clear that N is the midpoint of the diagonal KM.

so

KN = 1/2 KM

substitute KM = 47

KN = 1/2 × 47

KN = 23.5

Therefore, the value of KN = 23.5

Summary:

The value of x = 13

The value of KN = 23.5
