tolong dijawab y sama caranya

[tex] { DE}^{2} = EG \times EF \\ {12}^{2} = EG \times 16 \\ 144 = 16EG \\ \frac{144}{16} = \frac{16 EG}{16} \\ EG = 9 \\ \\ FG = EF - EG\\ = 16 - 9 \\ = 7 \\ \\ { DG}^{2} = GF \times GE \\ { DG}^{2} = 7 \times 9 \\ { DG }^{2} = 63 \\ DG = \sqrt{63} [/tex]

jawabannyaa A
smoga membntuu:)
