Triangle XYZ has congruent sides (of equal length 8 units, given).


So, this triangle is equilateral and equiangular: each its interior angle is  190/3 = 60 degrees.


ZW is the altitude from the vertex Z to side XY.


In the same time, ZW is the bisector of the angle Z and the median in triangle XYZ.


m∠WYZ = 60°


m∠YWZ = 90°


m∠YZW = 30°


ZW =  =  = 6.828  (rounded).


WY = half of XY = 8/2 = 4 units.
