Question

the movement of the progress bar may be uneven because questions can be worth more or less. which angle is an acute angle? ∠aoc ∠doc ∠eoc ∠boa

Explanation:

Step1: Recall acute - angle definition

An acute angle is an angle whose measure is between 0° and 90°.

Step2: Analyze each option

• $\angle AOC$: It is an obtuse - angle (greater than 90°).
• $\angle DOC$: From the figure, it is clearly between 0° and 90°, so it is an acute - angle.
• $\angle EOC$: It is an obtuse - angle (greater than 90°).
• $\angle BOA$: It is a right - angle (equal to 90°).

Answer:

$\angle DOC$
