Question

I don't know what it means by an obtuse angle. I have to choose math because I don't see a subject for shapes and stuff.

Answer 1

An obtuse angle is anything bigger than 90 degrees because 90 degrees is a right angle, therefore D. ADE would be the answer.

Answer 2

Angle ADE is an obtuse angle.

Explanation:

An obtuse angle is an angle that "opens" greater than 90 degrees. The question asks which angle is an obtuse angle, so basically you follow the order of letters and see which one is greater than 90 degrees (btw, 90 degrees, also known as a right angle, looks like the corner of a square, and anything greater than that is an obtuse angle).
