1)
10²=8²+w²
100=64+ w²
100-64=w²
36=w²
6=w
2)
[tex]20 {}^{2} =( 10 \sqrt{3} ) {}^{2} + k { }^{2} \\ 400 = 100 \times 3 + k {}^{2} \\ 400 - 300 = {k}^{2} \\ 100 = k {}^{2} \\ 10 = k[/tex]
3)
[tex]6 {}^{2} = 1 {}^{2} + y {}^{2} \\ 36 = 1 + y {}^{2} \\ 35 = y {}^{2} \\ \sqrt{35} = y[/tex]
4)
8²=6²+x²
64=36+x²
28=x²
[tex]8 {}^{2} = 6 {}^{2} + x {}^{2} \\ 64 = 36 + x {}^{2} \\ 28 = x {}^{2} \\ \sqrt{28 } = x \\ \sqrt{4 \times 7} = x \\ 2 \sqrt{7} = x[/tex]
[tex](2 \sqrt{7} ) {}^{2} + (1.2) {}^{2} = d {}^{2} \\ 4 \times 7 + 1.44 = d {}^{2} \\ 29.44 = d {}^{2} \\ \sqrt{29.44} = d \\ tu \: nie \: jestem \: pena \: czy \: jest \: dobrze[/tex]
5)
w tym nie widzę wszystkich danych
