Odpowiedź:
Zad 4
a) r=10
b)
[tex]r = 14 \\ s = 7 \sqrt{3} [/tex]
c)
[tex]r = 4.5 \\ s = 4 \frac{1}{2} \sqrt{3} [/tex]
d)
r=1
s=2
Zad 5
a)
[tex] \frac{7 \times 7 \sqrt{3} }{2} = \frac{49 \sqrt{3} }{2} = 24 \frac{1}{2} \sqrt{3} [/tex]
b)
[tex] \frac{8 \sqrt{3} \times 8}{2} = 4 \times 8 \sqrt{3} = 32 \sqrt{3} [/tex]
c)
[tex] \frac{6 \times 6 \sqrt{3} }{2} = 3 \times 6 \sqrt{3} = 18 \sqrt{3} [/tex]
