panjang bc adalah? pake cara yaa plisss :)

AB = √12²+9²
AB = √144+81
AB = √225
AB = 15

AC = √24²+7²
AC = √625
AC = 25

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

Gunakan pytagoras...

AB = √12²+9²
AB = √144+81
AB = √225
AB = 15 cm

AC = √24²+7²
AC = √576+49
AC = √625
AC = 25 cm

BC = √AC²-AB²
BC = √25²-15²
BC = √625-225
BC = √400
BC = 20 cm

Semoga membantu...
