A trapezoid is symmetrical about a vertical center line. If a circle is drawn such that it is tangent to exactly three sides of the trapezoid and is enclosed entirely within the trapezoid, what is the diameter of the circle

(1) The parallel sides of the trapezoid are 10 inches apart.
(2) Of the parallel sides of the trapezoid, the shorter side is 15 inches long.

Will appreciate an algebraic proof.

A couple of questions:

What level is this question

And is this an official GMAT question. I feel its too confusing and can easily be misinterpreted.

What does symmetrical about a vertical centre line mean?
