Explanation:

To determine the relationship between \(\angle XVY\) and \(\angle ZVY\), we analyze the diagram. We know that \(\angle XVZ\) is a right angle (90°) because of the right - angle symbol. Mathematically, \(\angle XVY+\angle ZVY = \angle XVZ\). Since \(\angle XVZ = 90^{\circ}\), by the definition of complementary angles (two angles whose sum is \(90^{\circ}\)), \(\angle XVY\) and \(\angle ZVY\) are complementary.

• Acute angles are angles less than \(90^{\circ}\), but this describes the measure of a single angle, not the relationship between two angles.
• A right angle is an angle of \(90^{\circ}\), and we are looking at a pair of angles, not a single angle.
• Supplementary angles are two angles whose sum is \(180^{\circ}\), which does not match the sum of these two angles.

Answer:

complementary
