  • BC =√25²-15² 
          =√625-225
         =√400
          =20 cm

    BD=√17²-15²
         =√289-225
         =√64
         = 8 cm

    CD =20-8=12 cm

    jwb.C

  • DB = √17²-15²
    =√289-225
    =√64
    =8
    CB = √25²-15²
    = √625-225
    = √400
    = 20
    CB-DB = 20-8
    =12 (C)
    maaf kalau salah^^
