What type of triangle is it?

Let us check the angle opposite the longest side.....we can use the Law of Cosines and the cosine inverse

900  =  100 + 576 - 2(100)(576)cosx

acos [ 900 - 100 - 576] / [ -2(10)(24) ]   =  x  =  about  117. 82°

So......it is obtuse

SInce it has three sides of unequal length and it is not a Right Triangle, I think I would call it a scalene triangle.
