1) In triangle $XYZ,$ $M$ is the midpoint of $\overline{XY}.$ Let $D$ be the point on $\overline{YZ}$ such that $\overline{XD}$ bisects $\angle YXZ,$ and let the perpendicular bisector of $\overline{XY}$ intersect $\overline{XD}$ at $P.$ If $XY = 36$ and $MP = 9,$ then find the distance from $P$ to line $XZ.$

2) In triangle ABC, AB=BC=17 and AC=16 Find the circumradius of triangle ABC
