itu yng coret2an bukan ya!! please yng bisa bantu klo bisa sekalian sma caranya nggak langsung jawaban

Soal No. 2

[tex]x= \sqrt{13^2-5^2}= \sqrt{169-25}= \sqrt{144}=12 [/tex]

Soal No. 3

[tex]x= \sqrt{10^2+10^2}= \sqrt{2\times(10^2)}= \sqrt{2} \times \sqrt{10^2}=10 \sqrt{2} [/tex]

Soal No. 4

[tex]72= \sqrt{x^2+ x^{2} } \\ \\ 72= \sqrt{2\times (x^2)} }\\ \\ 72= \sqrt{2}\times \sqrt{x^2} \\ \\ 72= x \sqrt{2} \\ \\ x= \frac{72}{\sqrt{2}} \times \frac{\sqrt{2} }{\sqrt{2} } \\ \\ x= \frac{72\sqrt{2} }{2} \\ \\ x=36\sqrt{2} [/tex]
