Question

which angle is an acute angle?
∠aoc
∠eoc
∠doc
∠bod

Explanation:

An acute angle is defined as an angle that measures greater than $0^\circ$ and less than $90^\circ$.

• $\angle AOC$ is a straight angle ($180^\circ$), not acute.
• $\angle EOC$ is a right angle ($90^\circ$), not acute.
• $\angle BOE$ is a straight angle ($180^\circ$), not acute.
• $\angle BOC$ is between $0^\circ$ and $90^\circ$, so it is acute.

Answer:

$\boldsymbol{\angle BOC}$
