35 students would not know any of the three languages, because if 30 know French, 19 knew German, and 16 knew Russian, that must mean that 65 students know at least one of the three languages. So you subtract 65 from 100 and end up with 35
Answer:
Step-by-step explanation:
the sum of the angles in a triangle is 180
33+2c+c-18=180
3c=180+18-33
3c=165
c=165/3
c=55
