Can someone me . work is due tomorrow .

Well it's similar because it uses the numbers to number the line and used as measurements and it's different because it has more precise measurements for whatever it is that u r doing

It is similar because it is by what number is least to greatest and it is different because one is by fractions and the other is by whole number 

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
