Step 1: Identify parallel lines and transversals. We are given that line PQ is parallel to line RS (PQ RS). We are also given that line QU is parallel to line PT (QU PT). The angle PSR = 42^. We need to find angle x, which is PQU. Step 2: Use the property of alternate interior angles with PQ RS. Consider the parallel lines PQ and RS intersected by the transversal QU. The angles PQU (which is x) and QUS are alternate interior angles. Therefore, they are equal: x = QUS Step 3: Use the property of
