Answer 2

B is obtuse.

Explanation:

There are five main types of angles:

• Acute: Angles less than 90.
• Right: Angles exactly 90.
• Obtuse: Angles more than 90 but less than 180.
• Straight: Angles exactly 180.
• Reflexive: Angles more than 180 but less than 360.

Angle B is obtuse because it is more than 90 degrees but less than 180.

Angle D is acute because it is less than 90 degrees.
