Which of the following are obtuse angles?
Angle I is definitely an obtuse angle.
As for angle II, it is not an obtuse angle. This is because this angle is less than 90°.
Angle III is not an obtuse angle as it is greater than 180°.
Angle IV is an obtuse angle as this angle is more than 90° and less than 180°.
Clearly, only I and IV are obtuse angles. Hence, the answer is B.
