Explanation:

  1. m <a+m <b+m <c=180 {sum of angles in a straight line are 180}
  2. 3x+5+5x-18+7x-2=180
  3. 15x-15=180
  4. 15x=180-15
  5. 15x=165
  6. x=165/15
  7. x=11
  8. so, m<a=3x+5=3×11+5=33+5=38

m<b=5x-18=5×11-18=55-18=37

m <c=7x-2=7×11-2=77-2=75

part B: no bcuz their sum isn't 90 whereas to be complement it must be 90
