bantuin dongggg kkkkkk!!!!
BC = 9 cm
Penjelasan dengan langkah-langkah :
[tex]\begin{aligned}{\sf{BC}}&={\sf{\sqrt{AB^2-CA^2}}}\\&={\sf{\sqrt{15^2-12^2}}}\\&={\sf{\sqrt{225-144}}}\\&={\sf{\sqrt{81}}}\\&={\sf{9~cm}}\end{aligned}[/tex]
Jawaban:
BC
= √AB² - CA²
= √15² - 12²
= √( 15 × 15 ) - ( 12 × 12 )
= √225 - 144
= √81
= 9 Cm
