    a) should be the other way around, so Kendra is correct It should be RW = 2/3*RU This is because the medians meet at a point which cuts each median into two parts that are 2:1 in ratio (ie one part is double the other)

    1a) In this triangle, the 3 perpendicular bisectors cross themselves @ the point W. So, you can write that : (1) : UW = (1/3)RU (2) : VW = (1/3)VS (3) : TW = (1/3)TQ You can see that : RW = RU - UW, but according to the equation (1) : UW = RU/3 RW = RU - (1/3)RU RW = (3/3)RU - (1/3)RU RW = [(3 - 1)/3]RU RW = (2/3)RU (2/3)RW = (2/3)(2/3)RU (2/3)RW = (4/9)RU So we can say that the Jordan's comment is wrong. Kendra disagrees. I'm not agree with Jordan. 1b) You can see that : QW = QT - TW, but according to the equation (3) : TW = (1/3)TQ QW = QT - (1/3)TQ QW = (3/3)QT - (1/3)TQ QW = (3/3)QT - (1/3)QT QW = [(3 - 1)/3]QT QW = [2/3]QT [2/3]QT = QW QT = (3/2)QW, if QW = 27 inches QT = (3/2) * 27 QT = 81/2 (inches)

    Part B is 81/2 or 40.5

    you can verify by taking 2/3 of QT = 40.5 to get QW = 27

    because its asking for Round to the nearest tenth if necessary. so for the part B it will be 40.5?
