The simplest pattern is 2n+1, so the 16th figure will have 33 triangles.
Of course, if you are creating new triangles and also keeping the old triangles, this would be different.
There are 33 triangles in a 35 sided polygon.

33
It is 82.5 percent. You figure it by dividing 33 into 40. 33/40=.825
33% is the same as 0.33 and 0.33*120 = 39.6
33%
yes
33% is the same as 0.33 and 0.33 times 62.8 = 20.724
The atomic number 33 is for arsenic (As); the nucleus contain 33 protons and 42 neutrons.

33% off is the same as 100% - 33% = 67% of the original figure: 33% off $40 = 67% of $40 = 67/100 x $40 = $26.80
