Answer:
B & C
Step-by-step explanation:
Acute angles are sharp-like angle - they are measured between 1° up to 89°. That means acute angles have measurement starting from 1 to 89.
The shape of acute angles, as said, they are namely sharp angles because their vertex and lines form sharp shape.
So what you have to do is to find angles that look like a sharp pencil/pen, probably something that can be understandable:
Sharp-looking measurements are:
Keep in mind that ∠GFE is really an acute angle, but ∠HFE is a right angle.
Let’s look into more types of angles as shown in choices:
- ∠DBC is an obtuse angle - it is the angle measurement between 91° up to 179°
- ∠MLK is a right angle - it is the angle measurement of exact 90° - keep in mind, only right angles can have measurement of 90°
Hence, acute angles are ∠GFE and ∠DBA
