cos alfa = 4/5
tg alfa = 3/4
ctg alfa = 4/3
b)
trzeci bok trójkąta wyliczamy z twierdzenia Pitagorasa :
12^2+5^2= c^2
144+25=c^2
c^2=169
c= 13
sin alfa= 12/13
cos alfa= 5/13
tg alfa = 12/5
ctg alfa = 5/12
c) znowu twierdzenie Pitagorasa :
a^2+8^2=17^2
a^2+64=289
a^2= 289-64= 225
a= 15
sin alfa = 8/17
cos alfa = 15/17
tg alfa = 8/15
ctg alfa = 15/8
liczę na naj :)
cos a = 4/5
tg a = 3/4
ctg a = 4/3
b) bok c:
c= 13
sin a = 12/13
cos a = 5/13
tg a = 12/5
ctg a = 5/12
c) bok b:
b = 15
sin a = 8/17
cos a = 15/17
tg a = 8/15
ctg a = 15/8
