Question Analysis

This question requires applying the Angle Bisector Equidistant Theorem. The main focus is using the congruence of the given angles to find the length of based on the relationship between and .

 

Key Concept Explanation

The Angle Bisector Equidistant Theorem states that if a point lies on the angle bisector of an angle, then it is equidistant from the two sides of the angle. Here, since , is the angle bisector of . Points on (such as ) have equal perpendicular distances to and , which means the segments and (perpendicular to the sides of the angle) are related by this property.

 

Step - by - Step Solution

1. Given that , we can conclude that is the angle bisector of .

2. and are the perpendicular distances from point (a point on the angle bisector
