Need asap plz these are the numbers you use. 15 27 28 31 34 42 52

im sorry but did you ever get the answer?

Okay so we know an acute angle has to be below a right angle (90 degrees). That being said it already eliminates A. No we're down to 3 options. The answer is between b or c. I'd rather say b because it's below 90 degrees so it's definitely a acute angle. But you have a 50/50 chance! Either b or c.
Hope I helped =^w^=
