    Since TA is 20. I started thinking about the Bisecting thing. And I am saying that AU is also 20. Because KP bisects in Angle TAU

    Well i kind of thought through it. Since the lesson is about Bisectors. I gave a thought that angle TAU was being bisected by KP. And if angle TAU was being bisected, and TA was 20; then AU must also be 20.

    that can be proved by proving triangles congruent just saying will not be enough IF u need to show your work.

    thats even simpler, AR bisects angle R
