Which of the following are acute angles? (Select all correct answers)
Show answer
45°, 89°, 30°, 1°

Obtuse
An obtuse angle measures more than 90° and less than 180°. Since 120° is between 90° and 180°, it is an obtuse angle.
If two angles are complementary and one angle is 35°, what is the other angle?
