Prosze bardzo trudne chociaz po 1 zadaniu pomozcie poniewaz nie ogarniam tego:( prosze!!
zad. 2.1
sin 30=5/b
1/2=5/b
b=2*5
b=10
tg 30 = 5/a
√3/3=5/a
a√3=15
a=15√3/3
a=5√3
zad 2.2
tg 45°=a/6
1=a/6
a=6
cos45°=6/c
√2/2=6/c
c√2=12
c=6√2
obw= a+b+c
obw=6+6+6√2 = 12+6√2 = 6*(2+√2)
zad 2.3
wzor na pole trojkata rownoramiennego = a²√3/4
wiec P= (3*2)²√3/4 = 6²√3/4 = 36√3/4 = 9√3
