Please help me... I'm desperate literally...

The sum of 3 consecutive integers is 36
A) Find the smallest integer using a tape diagram
B) Let n represent the smallest integer. Write an equation that can be used to find the smallest integer.
C) Determine if each value of n below is a solution to the equation in part (b)
i) n = 12.5
ii) n = 12
iii) n = 11

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

It equals 1373.5 that’s the solution
