Question 649581
Well, hello first problem!

Keep these vocabulary words in mind when doing these problems:

acute angle: 0-89 degrees
right angle: exactly 90 degrees
obtuse angle: 91-179 degrees
straight angle exactly 180 degrees

With that in mind, we take 98 degrees and see it is between 91 and 179 degrees. It is an obtuse angle!

Final Answer: [ D). Obtuse Angle]
