x = 8
Explanation:
AE = 3x - 4
EC = x + 12
SInce diagonals AC and DB intersect at E
it means the lines which meet at the intersection E are equal. A and C meet at E which gives AE and EC
AE = EC
3x - 4 = x + 12
collect like terms:
3x - x = 12 + 4
2x = 16
divide both sides by 2:
2x/2 = 16/2
x = 8
Answer:
x=28
Step-by-step explanation:
vertical angles are congruent
3x-12=72
3x=84
x=28

Based on the fact that the Polygon ABCD was translated, then the polygon that is a translation of it will be Polygon 3.
<h3>What polygon is the translation of Polygon ABCD?</h3>
When a shape is translated, it is taken as it is from one area of the coordinate plane, to another area of the plane.
This means that it doesn't change in height, or orientation.
The only polygon that still looks like Polygon ABCD is Polygon 3 which means that it is the translated version.
