Best ResponseYou've already chosen the best response.0First note that the measure of angle XST + Measure of angle XSZ form a straight line and therefore have a sum of 180 degrees. We can then state that angle XST is supplementary to angle XSZ. This indicates that angle XST is congruent to angle Y which is also supplementary to angle XSZ. We now can state that the triangles RXY and RTS are Congruent using Angle  Side  Angle. Since the Triangles are congruent, the corresponding parts are congruent. This means that angle YRX is congruent to angle XRT which indicates that RX is a bisector of the angle YRT..
