In his second fight Little Mac faces Von Kaiser. His score in the second round ended up being smaller than
6000 points. Write an inequality to represent his score
at the end of the second round.

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

Iknow one of the answers is a and maybe b but not 100% sure about b

Ya i could just need to know what type of math
