Answer:
PA = XA
Explanation:
Construction of an angle bisector,
1). Mark an arc from point W with the help of a compass which intersect lines WS and WZ at the points P and X respectively.
2). Marc two arcs of the same length form the points P and X which intersect each other at a point A.
3). Joint the points A and W.
Thus AW will be the angle bisector of angle PWX where PA = XA.
Therefore, distances PA and XA will be equal in measure.
