Question

DEFG is a rumbus. Find the vaule

Answer 1

Step-by-step explanation:

in a rhombus (not rumbus !) all sides are equally long.

that means

7x - 4 = 3x + 12

4x = 8

x = 2

Answer 2

Answer:

Step-by-step explanation:

The sides of a square are equal to each other, it is with the same with rhombus.

With this information, we can Say that $DE$ is equal to line $GD$, with
$DE =7x-4GD=3x+12$
$7x-4=3x+12$
Take $3x$ from both sides.
$4x-4=12$
Add 4 to isolate X
$4x=16$
Divide by 4
$x=4$

So we can say that the value of $x$ is 4
