trójkąt nr 1
2^2 + x^2 = 5^2
4 + x^2 = 25
25-4=21
[tex]\sqrt{21}[/tex]
5^2 + [tex]\sqrt{21}[/tex]^2 = x^2
25 + 21 = x^2
46 = x^2
x = [tex]\sqrt{46}[/tex]
5 + 2 + 7 + [tex]\sqrt{46}[/tex] = 14 + [tex]\sqrt{46}[/tex]
trójkąt nr 2
6^2 + x^2 = (2[tex]\sqrt{13}[/tex])^2
36 + x^2 = 4*13
36 + x^2 = 52
52 - 36 = 16
[tex]\sqrt{16}[/tex] = 4
4 + 4 + 6 + 10 = 24
