Re: In isosceles triangle XYZ, what is the measure of angle XZY? [#permalink]
statement 1 says angle xyz = 44 and we already know that the triangle is an isosceles triangle which means 2 angles have the same degrees. therefore xzy could be 2 possibilities .
xyz = 44 and yxz = 44 then xzy = 180- 44 -44 = 92 alternatively if xyz = 44 then other 2 angles can be 180-44 = 136/2 = 68 degrees no clear answer therefore not sufficient.

Statement 2 says angle yxz measures = 92 . which means no other angle can share its deminsions because if it does it exceeds 180 therefore the other 2 angle = part of isosceles.
zxy = 180-92 = 88/2 =44. sufficient .

Ans = B
