Final answer:
If one angle of a triangle is a right angle, then the other two angles are both acute. In this case, with a triangle having a 45 degree angle, we can conclude that the other two angles are also acute angles.
Step-by-step explanation:
In a triangle, if one angle is a right angle (90 degrees), then the other two angles are acute angles (less than 90 degrees). Since the given triangle has a 45 degree angle, which is less than 90 degrees, we can conclude that the other two angles are also acute angles.
