Answer 1

Jawaban:

17 cm

Penjelasan dengan langkah-langkah:

Panjang AC:

• AC = [tex] \sqrt{BA² + BC²}[/tex]
• AC = [tex] \sqrt{12² + 9²}[/tex]
• AC = [tex] \sqrt{144 + 81}[/tex]
• AC = [tex] \sqrt{225}[/tex]
• AC = 15 cm

Panjang AD:

• AD = [tex] \sqrt{AC² + DC²}[/tex]
• AD = [tex] \sqrt{15² + 8²}[/tex]
• AD = [tex] \sqrt{225 + 64}[/tex]
• AD = [tex] \sqrt{289}[/tex]
• AD = 17 cm

Answer 2

Verified answer

Teorema Pythagoras

..

[tex]\begin{aligned} Panjang AD &= \sqrt{(12~cm)^2 + (9~cm)^2 + (8~cm)^2} \\&= \sqrt{144~cm^2 + 81~cm^2 + 64~cm^2} \\&= \sqrt{225~cm^2 + 64~cm^2} \\&= \sqrt{289~cm^2} \\&= \boxed{\bold{\underline{17~cm}}} \end{aligned}[/tex]
