Question 198200: : xw is an angle bisector angle yxz=9x+38, angle wxy=10x-14, angle xzy=8x. find angle wzx. is xw an altitude?
Answer by RAY100(1637)   (Show Source):
You can put this solution on YOUR website! Bisector leads to 10x -14 = (1/2) (9x+38)
.
20x -28 = 9x +38
.
11x = 66
.
x=6
.
Subst in 8x = 48 = angle xzy
.
for xw to be altitude angle zwx must = 90 degrees,
.
triangle xzw, has angles, xzw =48, and zxw = 46, therefore zwx = 86, and not 90
.
therefore xw is NOT an altitude
