lesson: angle bisectors

Explanation:

Step1: Identify angle bisector property

QS is an angle bisector of $\angle RQP$, so the distances from S to the two sides of the angle are equal.

Step2: Match equal distances

The distance from S to QR is RS, and the distance from S to QP is SP = 17. By the angle bisector theorem for distances, these lengths are equal.

Answer:

17
