To solve for \( x \) in trapezoids, we typically use the formula for the median of a trapezoid, which is given by:
\[ M = \frac{b_1 + b_2}{2} \]
where \( M \) is the length of the median, and \( b_1 \) and \( b_2 \) are the lengths of the two parallel sides (bases) of the trapezoid.
Since you haven't provided specific figures or values for the bases and median, I can't perform calculations based on specific trapezoids. However, if you provide the lengths of the bases and the median for each trapezoid, I can help you solve for \( x \).
Please provide those values or clarify your question further.
