`120^(@)` is an example of an/a___________ angle.

Options

A. Acute
B. Obtuse
C. Right
D. Straight

Answer

To solve the question, "120^(@) is an example of an/a___________ angle," we will analyze the types of angles and determine which category 120 degrees falls into.

### Step-by-Step Solution:

1. **Understand the Types of Angles**:
- **Acute Angle**: An angle that is less than 90 degrees.
- **Right Angle**: An angle that is exactly 90 degrees.
- **Obtuse Angle**: An angle that is greater than 90 degrees but less than 180 degrees.
- **Straight Angle**: An angle that is exactly 180 degrees.

2. **Identify the Given Angle**:
- The angle given in the question is 120 degrees.

3. **Compare 120 Degrees with Angle Types**:
- Since 120 degrees is greater than 90 degrees, it cannot be an acute angle.
- It is also not a right angle because it is not equal to 90 degrees.
- We need to check if it is an obtuse angle.

4. **Determine if 120 Degrees is Obtuse**:
- 120 degrees is greater than 90 degrees and less than 180 degrees.
- Therefore, 120 degrees fits the definition of an obtuse angle.

5. **Conclusion**:
- Based on the analysis, we conclude that 120 degrees is an example of an obtuse angle.

### Final Answer:
120^(@) is an example of an obtuse angle.
