jawabannya adalah
(mohon pake caranya)​

Penjelasan dengan langkah-langkah:

[tex] \sqrt{a^{2} + {b}^{2} } = c[/tex]

c adalah sisi miring

[tex] \sqrt{(x + 3)^{2} + {x}^{2} } = 15[/tex]

pindahkan akar menjadi kuadrat

[tex](x + 3)^{2} + {x}^{2} = {15}^{2} [/tex]

[tex] {x}^{2} + 6x + 9 + {x}^{2} = 225[/tex]

[tex]2 {x}^{2} + 6x + 9 = 225[/tex]

[tex]2 {x}^{2} + 6x - 216 = 0[/tex]

[tex] {x}^{2} + 3x - 108 = 0[/tex]

faktorkan

[tex](x - 12) \: \: (x + 9)[/tex]

[tex]x = 12[/tex]

[tex]x = - 9[/tex]
