Answer
Option B is correct.
Angle Y = 68º
Step-by-step explanation
Similar triangles have the same set of angles in them.
All the corresponding angles are equal to each other.
So, if triangle ABC is similar to triangle XYZ
Angle A = Angle X
Angle B = Angle Y
Angle C = Angle Z
The order in which they are named determines the angles that are corresponding to each other.
So, if Angle B = 68º
Angle Y = Angle B = 68º
