You have to multiply whatever number your working with by 2
Acute is any angle that measures less than 90 degrees
so 20 degrees and 27 degrees would be acute
also any angle that measures more than 90 degrees is obtuse.
so 133 degrees is obtuse.
also just so you know right angles measure exactly 90 degrees.
The answer is D
-24 is less in value than -20
-20 is less in value than -18
-18 is less in value than -12
