a)h=6√3
b)h=(5√3):2
h=2,5√3
c)√3
h=√3*√3/2=3/2=1,5
d)4√6
h=4√6*√3/2=4√18/2=4√9*2/2=4*3√2/2=12√2/2=6√2
2)
h=4cm
a=2*4/√3 = 8/√3=8√3/3
a)P=a2√3/4
a2=4P/√3
4*√3/√3=a2
a2=4
a=2
a)12
h=12√3/2=6√3
b)5
h=5√3/2=2,5√3
c)√3
h=√3*√3/2=3/2=1,5

trzeba przekształcić wzór z wysokości, więc a=2h/√3
h=4cm
a=2*4/√3 = 8/√3=8√3/3
a)P=a2√3/4
a2=4P/√3
4*√3/√3=a2
a2=4
a=2
a) 6√3
b) 2,5√3
c) 1,5
d) 6√2

2 cm = a√3 | * √3
2 √3 cm = 3a
a = (2√3)/3 cm
a - bok
