Szczegółowe wyjaśnienie:
Zadanie 1
a) 3² + 8² = x²
9 + 64 = x²
x² = 73
x = √73
b) 2² + y² = (2√17)²
4 + y² = 68
y² = 64
y = 8
c) 6² + z² = 8²
36 + z² = 64
z² = 28
z = 2√7
Zadanie 2
a) a² + (√5)² = (√14)²
a² + 5 = 14
a² = 9
a = 3
b) 4² + 5² = b²
16 + 25 = b²
b² = 41
b = √41
Zadanie 3
7² + 6² = x²
49 + 36 = x²
x² = 85
x = √85 - D
Zadanie 4
3² + 5² = x²
9 + 25 = x²
x² = 34
x = √34 - A
Zadanie 5
x² + 5² = 13²
x² + 25 = 169
x² = 144
x = 12 - B
Zadanie 6
(3,5)² + (6,5)² = x²
12,25 + 42,25 = x²
x² = 54,5
x ≈ 7,4 km - A
