po opuszczeniu wysokosci powstaje trojk.prost a wys dzieli podstawe na pol wiec:
6²+h²=10²
h²=100-64
h²=36
h=6
b)
wzor na wys w trojk rownob to a√3/2
wiec:
10√3/2=5√3/2
h²=100 - 36
h²=64
h=√64
h=8
h²+5²=10²
h²=100-25
h=√75
h=5√3
cosβ=3/5
cosβ=√2/2
β=45*
sin45*=h/10
sin45*=√2/2
h/10=√2/2
2h=10√2 I:2
h=5√2
b)
cosβ=5/10
cosβ=1/2
β=60*
sin45*=h/10
sin45*=√2/2
h/10=√3/2
2h=10√3 I:2
h=5√3
