Jawaban:

Penyelesaian :

• AB = 8 cm
• BC = 6 cm
• GC = 12 cm

[tex] \sf {AG}^{2} = {AB}^{2} + {BC}^{2} + {GC}^{2} [/tex]

[tex] \sf {AG}^{2} = {8}^{2} + {6}^{2} + {12}^{2} [/tex]

[tex] \sf {AG}^{2} = 64 + 36 + 144[/tex]

[tex] \sf {AG}^{2} = 64 + 180[/tex]

[tex] \sf {AG}^{2} = 244[/tex]

[tex] \sf AG = \sqrt{244} \: cm[/tex]
