1)Lines PTQ and PUR are tangent to a circle, as shown below. If angle QTA = 41 degrees and angle RUA = 63 degrees, then find angle QPR, in degrees.
2) In rectangle EFGH, EH = 3 and EF = 4. Let M be the midpoint of EF, and let X be a point such that MH = MX and angle MHX = degrees. as shown below. Find angle XGH, in degrees.
3) In triangle ABC, M is the midpoint of AB. Let D be the point on BC such that AD bisects angle BAC, and let the perpendicular bisector of AB intersect AD at E. If AB = 44 and ME = 12, then find the distance from E to line AC.
