An angle of 120 degrees is which type?

Explanation:
An angle that measures 120 degrees is obtuse because it opens wider than a right angle but not all the way to a straight line. Acute angles are smaller than 90 degrees, a right angle is exactly 90 degrees, and a straight angle is exactly 180 degrees. Since 120 sits between 90 and 180, it fits the definition of an obtuse angle.
