  • A.

Step-by-step explanation:

An angle that measures greater than 90° is known as the obtuse angle. The angle measure ranges from 90° to 180°. An obtuse angle can also be found out if we have the measure of the acute angle. In the picture above, line segment DO intersects line segment OQ at point O and forms an angle DOQ measuring 120°.
