Answer:
∠ZXY = 57°
Step-by-step explanation:
According to angle sum property of a triangle, sum of all the angles of the triangle is [tex]180[/tex]°.
In ΔXYZ,
∠XYZ + ∠YZX + ∠ZXY = 180°
Put ∠XYZ = 104°, ∠YZX = 19°
104° + 19° + ∠ZXY = 180°
123° + ∠ZXY = 180°
∠ZXY = 180° - 123°
∠ZXY = 57°
Therefore,
∠ZXY = 57°
