Tolong ya kak pake cara

a)
[tex]x {}^{2} = 5 {}^{2} - 3 {}^{2} \\ x {}^{2} = 25 - 9 \\ x {}^{2} = 16 \\ x = \sqrt{16} = 4 \: cm[/tex]
b)
[tex]x {}^{2} = 8 {}^{2} + 6 {}^{2} \\ x {}^{2} = 64 + 36 \\ x {}^{2} = 100 \\ x = \sqrt{100} = 10[/tex]
c)
[tex]34 - 10 = 14 \\ x {}^{2} = 25 {}^{2} - 14 {}^{2} \\ x {}^{2} = 625 - 196 \\ x {}^{2} = 429 \\ x = \sqrt{429} = 20.71[/tex]
semoga membantu:)

semoga dapat membantu
