Odpowiedź:
a) 5^2 + 12^2 = x^2
25 + 144 = x^2
169 = x^2
13 = x
b) y^2 + 6^2 = 10^2
y^2 + 36 = 100
y^2 = 100-36
y^2 = 64
y = 8
c) 4^2 + z^2 = (3√2)^2
16 + z^2 = 18
z^2 = 18 - 16
z^2 = 2
z = √2
d) (3√3)^2 + (2√5)^2 = b^2
27 + 20 = b^2
47 = b^2
b = √47
e) (√11)^2 + c^2 = 5^2
11 + c^2 = 25
c^2 = 25 – 11
c^2 = 14
c = √14
