Answer:
Angle X must be Acute.
Angle Z must be Acute.
The sum of angles X and Z must be equal to 90°.
Step-by-step explanation:
Triangle XYZ is a right triangle with the right angle at vertex Y
∠Y=90°
We have two more angle of triangle ∠X and ∠Z
∠X+∠Y+∠Z=180° (Angle Sum property of triangle)
∠X+∠Z=180° -90° (∠Y=90°)
∠X+∠Z=90°
If sum of two angle is 90° then ∠X and ∠Z must be acute angle.
Therefore,
Angle X must be Acute.
Angle Z must be Acute.
The sum of angles X and Z must be equal to 90°
