<em>Greetings from Brasil</em>
Let us call the distance AB of Y (in the problem nothing is said about this dimension, so lets call of Y).
From the attached drawing we can conclude that:
AB + BC = AC
where
AB = Y
BC = 2X + 4
AC = 24
then
AB + BC = AC
Y + (2X + 4) = 24
<h2>X = (20 - Y)/2</h2><em>In my view this question is incomplete</em>
Answer:
Explanation:
1) The two parallel sides of different legths and
constitute the bases of a trapezoid.
2) The two equal anglesare the base angles of the trapezoid, and mean that it is an isosceles trapezoid.
An isosceles trapezoid is truncated isosceles triangle.
The definition of trapezoid is a quadrilateral with at least two parallel sides.
The drawing is attached: only the green lines represent the figure, the dotted lines just show how this is derived from an isosceles triangle.
