+87 1. The area of trapezoid \(PQRS\) is \(60\). One base is \(7\) units longer than the other, and the height of the trapezoid is \(5\). Find the length of the median of trapezoid \(PQRS\).
2. In trapezoid \(WXYZ, \overline{XY} \parallel \overline{WZ}, \angle WXZ = 105^\circ, \angle W = 43^\circ,\)and \(\angle Y = 141^\circ\). Find \(\angle YXZ\), in degrees.
