Ross is comparing 11 squared and 5.4 repeating. he says that 11 squared is more than 5.4 repeating because 11 squared = 5.5. what mistake did ross likely make? (edit: nvm already found the answer, his proofing was wrong he divided it instead of multiplying it by itself and getting 121)

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
