∠ Z = 1°
Step-by-step explanation:
Since the shape is a triangle it means that all it's interior angles sum to 180°
To find the missing angle sum up the known angles and subtract them from 180°
That's
[tex]\angle X + \angle Y + \angle Z = 180°[/tex]
[tex]89° + 90° + \angle Z = 180°[/tex]
[tex]\angle Z = 180 - 179°[/tex]
We have the final answer as
[tex]\angle Z = 1°[/tex]
