Respuesta :


10x + 7 = 2x + 41
8x + 7 = 41 
8x = 34 
x = 17/4

Answer:

[tex]x=\dfrac{17}{4}[/tex] .

Step-by-step explanation:

It is given that ABCD is an isosceles trapezoid and it has diagonals AC = 10x + 7 and BD = 2x + 41.

We need to find the value of x.

We know that the diagonals of an isosceles trapezoid are equal.

[tex]AC=BD[/tex]

[tex]10x+7=2x+41[/tex]

[tex]10x-2x=41-7[/tex]

[tex]8x=34[/tex]

[tex]x=\dfrac{34}{8}[/tex]

[tex]x=\dfrac{17}{4}[/tex]

Hence the value of x is [tex]\dfrac{17}{4}[/tex].
