Whole plane consists of 360°


\\ \sf\longmapsto x+5+x+45+90+3x+6=360


\\ \sf\longmapsto 5x+146=360


\\ \sf\longmapsto 5x=360-146


\\ \sf\longmapsto 5x=214


\\ \sf\longmapsto x=214/5


\\ \sf\longmapsto x\approx 43

  • m<DBE=3(43)+6=135
  • m<ABF=90°

Somehow error present in diagram.(90° sign must not be x)
