which two angles relationships can only be an exact number?
select the correct answer
obtuse, acute
all of the answers
right, straight

Explanation:

To determine the answer, we analyze angle relationships:

• Obtuse angles are greater than \(90^\circ\) but less than \(180^\circ\) (range, not exact single number). Acute angles are less than \(90^\circ\) (range, not exact single number).
• A right angle is exactly \(90^\circ\), and a straight angle is exactly \(180^\circ\). These have fixed, exact measures. So "Right, Straight" are the angle relationships with exact numbers.

Answer:

Right, Straight
