Question

88 degrees; options: obtuse, right, straight, acute

Explanation:

Step1: Recall angle definitions

• Acute angle: $0^\circ < \theta < 90^\circ$
• Right angle: $\theta = 90^\circ$
• Obtuse angle: $90^\circ < \theta < 180^\circ$
• Straight angle: $\theta = 180^\circ$

Step2: Compare 88° with definitions

Given angle is $88^\circ$. Since $0^\circ < 88^\circ < 90^\circ$, it fits the acute angle definition.

Answer:

acute (along with its option identifier if applicable, but since the options are labeled with their terms, the correct one is the "acute" option)
