zad 1
a)
a = 8
przekątna kwadratu = a√2 = 8√2
b)
a = 4√2
przekątna = 4√2 * √2 = 4 * 2 = 8 cm
zad 2
a² = 10² - 6² = 100 - 36 = 64
a = √64 = 8
P - pole = a * 6/2 = 8 * 6/2 = 48/2 = 24
p - obwód = 6 + 8 + 10 = 24
1. 8 do 2 +8 do 2 =a pierwiastek 2 do 2
64+64=2a do 2
128=2 a do 2 / 2
64=a do 2
8=a
2. a=8
ob=6+10+8=24
